Question

What is a codon sequence?

Answer 1

Codon sequence:

1. Codon is a trinucleotide sequence present in mRNA.
2. It is the sequence of bases in mRNA, that codes for a particular amino acid in the protein synthesis
3. Each code is made up of three nucleotides called a triplet. codons are nearly universal, except for some protozoans and mitochondrial codons
4. More than one triplet codon code for the same amino acid, so the code is degenerate
5. There are a total of 64 codons, of which 61 code for amino acids
6. 3 codons do not code for any amino acids, they are called stop codons- UAA, UAG, UGA.
7. AUG is the start codon as well as codes for the amino acid methionine.
