This is the gene described in The Selfish Gene. [9] More thorough discussions of this version of a gene can be found in the articles Genetics and Gene-centered view of evolution. The molecular gene definition is more commonly used across biochemistry, molecular biology, and most of genetics—the gene that is described in terms of DNA sequence. [1]
Genetics is the study of genes, genetic variation, and heredity in organisms. [1] [2] [3] It is an important branch in biology because heredity is vital to organisms' evolution.
Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes.
One of multiple alternative versions of an individual gene, each of which is a viable DNA sequence occupying a given position, or locus, on a chromosome. For example, in humans, one allele of the eye-color gene produces blue eyes and another allele of the same gene produces brown eyes. allosome. Also sex chromosome, heterochromosome, or ...
The term genome was created in 1920 by Hans Winkler, [8] professor of botany at the University of Hamburg, Germany.The website Oxford Dictionaries and the Online Etymology Dictionary suggest the name is a blend of the words gene and chromosome.
A second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965).
Gene nomenclature is the scientific naming of genes, ... (rules for gene naming and meaning of other symbols used in Molecular Biology) on EcoliWiki, ...
A regulator gene may encode a protein, or it may work at the level of RNA, as in the case of genes encoding microRNAs. An example of a regulator gene is a gene that codes for a repressor protein that inhibits the activity of an operator (a gene which binds repressor proteins thus inhibiting the translation of RNA to protein via RNA polymerase).
