How can telomerase replicate the ends of chromosomes without a template on the DNA being replicated?
It forms a loop and copies the DNA in that loop.
It carries its own DNA template.
It carries its own RNA template.
It simply connects the two ends of the chromosome. This statement is false - telomerase, like all other DNA polymerases must have a template on the strand that is being copied.
Solution
Answer=
Telomerase replicate the ends of DNA without the template on the DNA being replicated
It carries its own RNA template
Explaination= telomerase enzyme is a ribonucleoprotein,contains RNA & protein
it resembles reverse transcriptases,enzyme that synthesizes DNA using RNA template
telomerase recognizes the tip of G rich strand of an existing telomere DNA repeat, sequence & elongates it in the 5 prime to 3 prime directions.
The telomerase synthesizes a new copy of the repeat ,using an RNA template that is a component of enzyme itself
