Start and stop codons are found both on the original DNA strand in the nucleus of the cell and on the messenger RNA strand that serves as the protein template. The mRNA that corresponds to a specific gene on the DNA strand is synthesized in the nucleus using the antisense strand of DNA as a guide to...What is the definition of a stop codon?
stop codon. [stŏp] Any of three codons in a molecule of messenger RNA that do not code for an amino acid and thereby signal the termination of the synthesis of a protein.What is RNA stop codon?
Stop codon. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain.What are termination codons?
Termination codons. termination codon. (Science: molecular biology) The three codons, UAA known as ochre, UAG as amber and UGA as opal, that do not code for an amino acid but act as signals for the termination of protein synthesis. They are not represented by any tRNA and termination is catalysed by protein release factors.
