Answer:
The correct answer will be option-Telomerase is an enzyme that increases the length of linear chromosome ends
Explanation:
Telomerase is a reverse transcriptase enzyme which adds the length of DNA by adding the guanine-rich repetitive sequences called telomeres at 3' end of the DNA.
The enzyme not only adds the telomere but also maintain its length in the organism. The telomerase activity possesses several roles one of which is that it protects the end of the DNA from DNA damage and neighbouring chromosomes.
Since telomerase adds the repetitive sequences at the end and thus increases the length of the DNA thus is the correct answer.
Destruction of cells by viral reproduction.
