Solution

Histone chaperones play a role in replication by:

preventing nonspecific interactions between the positively charged histones and negatively charged DNA.

Explanation:

Histone chaperones shield non-specific interactions between the negatively charged DNA and the positively charged histones, to allow the ordered formation of the nucleosome structure.

telomerase may play a role in aging and cancer.

Telomeres consist of :

long TG-rich repeats at the ends of the linear chromosomes

the sequence of nucleotides in telomeres is TTAGGG

Telomerase is a _____________________.

reverse transcriptase

Telomerase is an RNA-dependent DNA polymerase, meaning an enzyme that can make DNA using RNA as a template.
