A proteogenomic toolkit

... Proteomic identifications rely on a comprehensive database in order to perform searches on mass spectra. The available proteomes, even for model organisms, are often incomplete [3]. Furthermore, these reference proteomes can never contain sequences that arise somatically and drive disease. RNA-seq e ...

RNA codons and correlant Amino Acids

... Thus, although the numbers per amino acids range between 8-24, it is evident that each amino acid has a distinct probability and thus cannot be modelled by uniform. From this graph, we can see that amino acids with more possible codons have a higher frequency, whilst those with smaller possible codo ...

Molecular evolution

Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.
