Question

What is the genetic code?

Answer 1

GENETIC CODE

✏ The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of DNA or mRNA is called genetic code.

CHARACTERISTICS OF GENETIC CODE

• ✏ Triplet Codon

• ✏ Non Overlapping

• ✏ Commaless

• ✏ Specificity

• ✏ Degenerate

• ✏ Universal

• ✏ Initiation Codon or Start Codon

• ✏ Termination Codon

✏ Out of 64 codons, only three are stop codon.

✏ Only two codon specify a single amino acid.

✏ They are AUG for methionine and UGG for tryptophan.

✏ Three amino acids have six codons each.

✏ Five amino acid have four codons.
