Furthermore, Acinetobactor baylyi ADP1 like most organisms undergoes a process known as DNA recombination, where two complementary DNA strands cross and exchange portions of DNA. During recombination, a structure known as a Holliday Junction forms and must be resolved, completing the exchange of DNA . Recombination is a crucial mechanism in both gene amplification and deletion. Specifically, ADP1 contains a protein called YqgF, a putative Holliday Junction Resolvase, due to its structural similarity to a known resolvase named RuvC (Aravind et al.

These led her to the idea that maybe the DNA molecule was coiled into a helical shape. Linus Pauling, the US chemist, and author of The nature of the chemical bond, began to think along similar lines. After all, Pauling had already discovered helical motifs in protein structures. Around this time, Francis Crick – with a background in maths and physics, and the younger James Watson, with expertise in the molecular biology of phage , joined forces at the Cavendish Laboratory in Cambridge, intent on cracking the DNA structure themselves, using a model building

Starting Materials: The Chemical Elements Of Life
Around two dozen chemical elements are essential to various kinds of biological life. Most rare elements on Earth are not needed by life , while a few common ones are not used. Most organisms share element needs, but there are a few differences between plants and animals. For example, ocean algae use bromine, but land plants and animals do not seem to need any. All animals require sodium, but some plants do not. Plants need boron and silicon, but animals may not .
Just six elementsâcarbon, hydrogen, nitrogen, oxygen, calcium and phosphorusâmake up almost 99% of the mass of living cells, including those in the human body . In addition to the six major elements that compose most of the human body, humans require smaller amounts of possibly 18 more.
The 4 main classes of molecules in bio-chemistry are carbohydrates, lipids, proteins, and nucleic acids. Many biological molecules are polymers: in this terminology, monomers are relatively small macromolecules that are linked together to create large macromolecules known as polymers. When monomers are linked together to synthesize a biological polymer, they undergo a process called dehydration synthesis. Different macromolecules can assemble in larger complexes, often needed for biological activity.
What Is The Difference Between Biochemistry And Chemistry
Biochemistry studies the chemistry of life — how life works at the molecular level, what kinds of chemical reactions occur in cells, and how these reactions give an organism its observed characteristics. The field overlaps in many areas with disciplines like molecular biology and genetics. A great deal of chemistry knowledge is involved — especially knowledge of organic chemistry since most of the important reactions that take place in organisms involve carbon compounds. Inorganic chemistry is involved as well, however, since many enzymes have metal-ion cofactors.
Chemistry comprises several distinct subdisciplines, namely, physical, inorganic and organic chemistry. In some ways, it’s a broader field than chemistry, since it’s concerned with the structure and behaviour of matter and the types of reactions compounds can undergo. The dividing line between biochemistry and chemistry is a little fuzzy, but in general, chemists are interested in designing useful new materials, finding more efficient ways to synthesize existing materials, or understanding why substances have the property that they do, while biochemists use chemistry to understand why and how certain processes take place in living organisms.
Molecular Biology Biochemistry And Genetics
Molecular biology is one of the newest and modern branches of science and scientific research, which concerns and deals with all biological activities at the lowest molecular level. Moreover, it overlaps and mixes with other fields of science from chemistry and biology, to biochemistry and genetics. The main area and aspect of its research is understanding how all cellular systems interact. To understand that, one has to think in terms of the most important particle of all human beings DNA, and of course, RNA and other proteins and all of their functions of synthesis. That is why biochemistry, genetics and molecular biology are hard to distinguish.
However, if you want to define what the scientists in those three fields are doing independently, it should be noted that a biochemist deals and studies chemical materials and processes that happen in all living organisms. They study the functions, structures and roles of biomolecules, which are the main focus of all biochemists. Other important area of focus is the chemistry of all biological functions and the synthesis of every biomolecule involved in living organisms.
Lastly, genetics concerns with genes and their effects on all living organisms. Those effects are mostly examined throughout knock-out studies, where researchers use models designed on animal so that they lack some of their genes compared to a regular phenotype.

Difference Between Biochemistry And Molecular Biology
Biology is the field of science that studies living organisms and their vital processes. It is subdivided into different branches covering all aspects of organisms such as morphology, physiology, anatomy, behavior, origin, and distribution of living organisms. Biochemistry and molecular biology are two such disciplines, dealing with the structure, function of biologically important molecules and their reactions.
The main difference between biochemistry and molecular biology is that biochemistry is the science that deals with the chemistry of living things, while molecular biology is the study of living things at a molecular level. A major in both these fields of biology trains you in the experimental techniques used to probe and study different structures and functions of biologically important molecules.

Chemistry Chemical Biology And Biochemistry
What is chemical biology, and how does it differ from biochemistry?
Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
Both programs start with a core of general chemistry, organic chemistry, genetics, cell biology, physics and introductory biochemistry. The chemical biology degree is very flexible you can tailor your program to take graduate level courses in organic chemistry, medicinal chemistry, bioinorganic chemistry and materials science. The biochemistry major offers a smaller set of rigorous courses in macromolecular chemistry, mechanism and structure. Both majors allow some electives to be chosen for upper level biology courses.
As for employment, you can get a job in the pharmaceutical/biotech industry with either major. With the chemical biology major, you would be the person designing and synthesizing the drug candidates, while with a biochemistry major, you would be the person designing assays to test the drug candidates.

Macromolecule Blotting And Probing
The terms northern, western and eastern blotting are derived from what initially was a molecular biology joke that played on the term Southern blotting, after the technique described by Edwin Southern for the hybridisation of blotted DNA. Patricia Thomas, developer of the RNA blot which then became known as the northern blot, actually didn’t use the term.
Named after its inventor, biologist Edwin Southern, the Southern blot is a method for probing for the presence of a specific DNA sequence within a DNA sample. DNA samples before or after restriction enzyme digestion are separated by gel electrophoresis and then transferred to a membrane by blotting via capillary action. The membrane is then exposed to a labeled DNA probe that has a complement base sequence to the sequence on the DNA of interest. Southern blotting is less commonly used in laboratory science due to the capacity of other techniques, such as PCR, to detect specific DNA sequences from DNA samples. These blots are still used for some applications, however, such as measuring transgene copy number in transgenic mice or in the engineering of gene knockoutembryonic stem cell lines.
The eastern blotting technique is used to detect post-translational modification of proteins. Proteins blotted on to the PVDF or nitrocellulose membrane are probed for modifications using specific substrates.

Definition Of Microbiology And Molecular Biology
Microbiology: Microbiology is the study of microorganisms including viruses, bacteria, fungi and protozoa.
Molecular biology: Molecular biology is the study of biological activities at molecular level, and this mainly concerns various interactions between the different types of biological systems like DNA, RNA, proteins and their biosynthesis.
Difference Between Molecular Biology And Genetics
Like Biochemistry, Molecular Biology deals with the structure and function of proteins and how genes are expressed in cells. Molecular Biology takes genes further by considering genetic approaches to things . Genetics covers most of the same genetic parts of Molecular Biology and also includes a non-molecular part like evolutionary Genetics, population Genetics etc.
Molecular Biology is more like investigating and figuring out metabolic pathways. Genetic engineering is more manipulative, trying to alternate such pathways as in trying to get plants to produce more food per unit.

Techniques Of Molecular Biology
One of the most basic techniques of molecular biology to study protein function is molecular cloning. In this technique, DNA coding for a protein of interest is cloned using polymerase chain reaction , and/or restriction enzymes into a plasmid . A vector has 3 distinctive features: an origin of replication, a multiple cloning site , and a selective marker usually antibiotic resistance. Located upstream of the multiple cloning site are the promoter regions and the transcription start site which regulate the expression of cloned gene.This plasmid can be inserted into either bacterial or animal cells. Introducing DNA into bacterial cells can be done by transformation via uptake of naked DNA, conjugation via cell-cell contact or by transduction via viral vector. Introducing DNA into eukaryotic cells, such as animal cells, by physical or chemical means is called transfection. Several different transfection techniques are available, such as calcium phosphate transfection, electroporation, microinjection and liposome transfection. The plasmid may be integrated into the genome, resulting in a stable transfection, or may remain independent of the genome, called transient transfection.
