Identify the type of mutation that occurred and explain in what way it affected the protien
Ira Lisetskai [31]

Answer:

The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.

Explanation:

The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.

In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.

Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
