Question

On which segment of human chromosome is the enzyme reverse transcriptase located

Answer 1

Answer:

Explanation:

Telomerases are part of a distinct subgroup of RNA-dependent polymerases. Telomerase lengthens telomeres in DNA strands, thereby allowing senescent cells that would otherwise become postmitotic and undergo apoptosis to exceed the Hayflick limit and become potentially immortal, as is often the case with cancerous cells. To be specific, TERT is responsible for catalyzing the addition of nucleotides in a TTAGGG sequence to the ends of a chromosome’s telomeres.[7] This addition of repetitive DNA sequences prevents degradation of the chromosomal ends following multiple rounds of replication
