Silent mutations, also called synonymous or samesense mutations, are mutations in DNA that do not have an observable effect on the organism's phenotype. The phrase silent mutation is often used interchangeably with the phrase synonymous mutation ; however, synonymous mutations are not always silent, nor vice versa.
A nonsynonymous substitution is a nucleotide mutation that alters the amino acid sequence of a protein.Nonsynonymous substitutions differ from synonymous substitutions, which do not alter amino acid sequences and are (sometimes) silent mutations.
Point substitution mutations of a codon, classified by their impact on protein sequence. A synonymous substitution (often called a silent substitution though they are not always silent) is the evolutionary substitution of one base for another in an exon of a gene coding for a protein, such that the produced amino acid sequence is not modified.
Hermann J. Muller (1890–1967), who was a 1946 Nobel Prize winner, coined the terms amorph, hypomorph, hypermorph, antimorph and neomorph to classify mutations based on their behaviour in various genetic situations, as well as gene interaction between themselves. [1] These classifications are still widely used in Drosophila genetics to ...
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution. It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
This category relates to specifically sociological terms and concepts. Wider societal terms that do not have a specific sociological nature about them should be added to social concepts in keeping with the WikiProject Sociology scope for the subject.
The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. [ 1 ] [ 2 ] [ 3 ] Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book On the Origin of Species . [ 4 ]
Monoallelic gene expression (MAE) is the phenomenon of the gene expression, when only one of the two gene copies is actively expressed (transcribed), while the other is silent. [ 1 ] [ 2 ] [ 3 ] Diploid organisms bear two homologous copies of each chromosome (one from each parent), a gene can be expressed from both chromosomes (biallelic ...
