Question

What is the definition of a codon?

Answer 1

Codon:

1. A three-nucleotide sequence that codes for a specific amino acid in a DNA or RNA molecule.
2. Codons indicate whether the translation should begin or cease.
3. Start and stop (or termination) codons are used for the initiation and termination of translation of mRNA.
4. The order of amino acids in the encoded protein is determined by the codon sequence in the mRNA.
5. Codons are start/stop signals that are present in addition to amino acids.
6. Each codon is made up of three contiguous nucleotides (also known as triplets) in mRNA that base-pair with the three bases of the anticodon of a tRNA molecule carrying a specific amino acid.
7. Binding sites can be found on the ribosome, which is where protein synthesis takes place. ‌
