REPLICATION
1. Telomerase, an enzyme with both RNA a protein components, lengthens the telomeres at the end of eukaryotic chromosomes.
a. (1 PT) What is the biological role of telomeres?
b. (2 PTS) Why is there a need for a special enzyme to assist with the replication of chromosome ends?
c. (1 PT) Does the telomerase enzyme use an RNA or DNA template when it adds the nucleotides to a DNA strand?
d. (1 PT) Does telomerase add ribonucleotides or deoxyribonucleotides?
e. (1 PT) Does the telomerase enzyme add nucleotides to the under-hang or the overhang of the chromosome ends?
f. (1 PT) Which enzyme completes the extension of the 5â end of the DNA molecule? g. (2 PTS) What is the effect of cancer on telomere length?
