1) a) in one sentence only, how is telomerase activity different from dna polymerase activity during dna elongation? b) in one sentence only, how is helicase activity different from telomerase activity.

1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in  five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.

2. During DNA elongation, helicase enzyme separates the double stranded DNA  into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.

Ithink its c hope it : )
