While there is much commonality, different parts of the tree of life use slightly different genetic codes. [1] When translating from genome to protein, the use of the correct genetic code is essential. The mitochondrial codes are the relatively well-known examples of variation.
The Protein Naming Utility, a rules database for protein nomenclature; Coli Genetic Stock Center is responsible for bacterial genetic nomenclature pertaining to Escherichia coli. Escherichia coli genetic nomenclature (rules for gene naming and meaning of other symbols used in Molecular Biology) on EcoliWiki, the community annotation system of ...
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets or codons) into proteins. Translation is accomplished by the ribosome , which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA ...
A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. [2] [3] The mRNA sequence is determined by the sequence of ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
1. A membrane protein that functions as a transporter, binding to a solute and facilitating its movement across the membrane by undergoing a series of conformational changes. [6] 2. A protein to which a specific ligand or hapten has been conjugated and which thereby carries an antigen capable of eliciting an antibody response. [12] 3.
In bioinformatics and biochemistry, the FASTA format is a text-based format for representing either nucleotide sequences or amino acid (protein) sequences, in which nucleotides or amino acids are represented using single-letter codes. The format allows for sequence names and comments to precede the sequences.
In spite of the fact that both protein-coding genes and noncoding genes have been known for more than 50 years, there are still a number of textbooks, websites, and scientific publications that define a gene as a DNA sequence that specifies a protein. In other words, the definition is restricted to protein-coding genes.
