Molecular Genetics. Genetics seems rather intimidating, but in its purest sense it is rather simple. The basis of genetics is fairly simple: DNA => RNA => A Protein. The Department Of Molecular Genetics Holds A Leadership Position In Canada And Internationally. It Is A Premier Venue For Biomedical And Life Sciences. Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level and thus employs methods of both molecular biology and genetics. The study of chromosomes and gene expression of an organism can give insight into heredity, genetic variation, and mutations.‎Technique · ‎Genetic screens · ‎The Human Genome Project · ‎See also.

RNAs serve as the working set of blue prints for a gene.

Molecular genetics - Wikipedia

Each gene is read, molecular genetics then the messenger RNAs are sent to the molecular factories ribosomes that build proteins. These factories read the blueprints and use the information to make the appropriate protein.

When the cell no longer needs to make any more of that protein, the RNA blueprints are destroyed. The gene is molecular genetics and the RNA takes the molecular genetics or blueprint to the ribosomes where melanin, the protein that tans your skin, is made.

Molecular Genetics

DNA Mutations As we discussed, each gene is made up of a series of bases and those bases provide instructions for making a molecular genetics protein.

Any change in the sequence of bases may be considered a mutation. That small difference from the original DNA sequence is a mutation. Mutations can also be caused by exposure to specific chemicals, metals, viruses, and radiation. These have the potential to modify the DNA.

The stability of DNA is primarily dependent on the strong covalent bonds that connect the constituent atoms of its linear backbone, and also on molecular genetics number of weak non-covalent bonds that exist.

Meanwhile, because of the phosphate group charges present in each nucleotide, DNA is negatively charged and therefore highly soluble in water.

Another approach is to construct a new, molecular genetics conception of biological information and use this conception to show that the informational role of genes is not exclusive Jablonka A different approach is to abandon information talk altogether and explain the investigative and explanatory reasoning associated with genetics and molecular biology in purely causal terms.

Keller points out molecular genetics the idea flounders on an ambiguity.

Oyama suggests that it is a mistake to think information is contained within static entities such as DNA. She believes that information exists in life-cycles. Other criticisms challenge applications of particular conceptions or theories of information, including applications of the causal and teleosemantic conceptions.

Molecular genetics distinguishes between molecular genetics ways to conceive of information, causal and intentional, and then argues that under either conception, information is not restricted to DNA.

Causal theories of information, based on Dretske'sare related to the Shannon mathematical theory of information Dretske distinguishes between a source variable and background or channel conditions.

On Griffiths' reading of Dretske's theory, a source variable, X, carries information about variable Y if the value of X is correlated with the value molecular genetics Y. Griffiths describes the causal interpretation of this idea as follows: There is a channel between two systems when the state of one is systematically causally related to the other, so that the state of the sender can be discovered by observing the state of the receiver.

The causal information is simply the state of affairs with which it reliably correlates molecular genetics the other end of molecular genetics channel. Thus, smoke carries information about fire and disease phenotypes carry information about disease genes.

It follows that genes carry information about phenotypes because phenotypic values reliably correlate with genotypic values.

But as Molecular genetics points out, nothing stops one from treating environmental conditions as source variables and genes as channel. Under this application of the causal theory, environmental conditions carry information about phenotypes.

Griffiths and others have concluded that the idea that genes provide the information while molecular genetics causal factors merely provide material cannot be sustained under causal theories of information. Griffiths argues that the idea that genes and DNA provide all the information fares molecular genetics better under intentional theories of information.
