  2. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    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.

  3. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates. These amino ...

  4. FASTA format - Wikipedia

    en.wikipedia.org/wiki/FASTA_format

    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.

  5. Amino acid replacement - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_replacement

    Some amino acids are more likely to be replaced. One of the factors that influences this tendency is physicochemical distance. Example of a measure of amino acid can be Graur's Stability Index. [9] The assumption of this measure is that the amino acid replacement rate and protein's evolution is dependent on the amino acid composition of protein.

  6. Translation (biology) - Wikipedia

    en.wikipedia.org/wiki/Translation_(biology)

    degradation of proteins. The process of amino acid building to create protein in translation is a subject of various physic models for a long time starting from the first detailed kinetic models such as [26] or others taking into account stochastic aspects of translation and using computer simulations. Many chemical kinetics-based models of ...

  7. Conservative replacement - Wikipedia

    en.wikipedia.org/wiki/Conservative_replacement

    A conservative replacement (also called a conservative mutation or a conservative substitution or a homologous replacement) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size). [1] [2]

  8. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    The two amino acid residues are linked through a peptide bond. As both the amine and carboxylic acid groups of amino acids can react to form amide bonds, one amino acid molecule can react with another and become joined through an amide linkage. This polymerization of amino acids is what creates proteins.

  9. Biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Biosynthesis

    In addition to binding an amino acid, tRNA has a three nucleotide unit called an anticodon that base pairs with specific nucleotide triplets on the mRNA called codons; codons encode a specific amino acid. [55] This interaction is possible thanks to the ribosome, which serves as the site for protein synthesis.
