Answer:
(C). the segment of DNA that is damaged is transcribed into RNA.
Step-by-step explanation:
A mutation is a permanent change in DNA caused by alteration in its nucleotide sequence. When a segment of a DNA (a gene) gets mutated, it will lead to formation of a mutated protein.
This is because the mutated sequence will form mRNA with altered sequence as DNA provides template for RNA sequence. Now, in altered mRNA the codon sequence will be changed from the sequence present in normal mRNA for that gene.
Hence, the protein translated by that mutated mRNA will also be mutated or non-functional.
Thus, the correct answer is option (C).
