The DNA sequence TTG is changed to TCG and produces a new protein. Which type of mutation is this?
missense
nonsense
silent
frameshift

missense

Explanation:A missense mutation is a type of mutation in which there is a change in one single nucleotide in a DNA sequence which results in an altered mRNA sequence and consequent incorporation of wrong amino acid into the amino acid sequence of a protein. The single nucleotide change in DNA results in a different codon on the mRNA sequence and this leads to production of a protein that is different from the original protein. This change can affect the function of the protein, in most cases it makes the protein nonfunctional.
