A point mutation changes the dna sequence cga to cgt

Asked by admin @ in Biology viewed by 402 People

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? nonsense missense silent frameshift

Answered by admin @


The correct answer is silent mutation . In this type of mutation there is no change in  the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .
