Question

Without helicase the chromosomes would progressively shorten with each replication.

true or false

Answer 1

Without helicase the chromosomes would progressively shorten with each replication. ___ False.

Helicase is a class of enzyme found in all organisms . Its main function is to unwind the gene of organisms. During replication it unwinds the double stranded DNA into single stranded DNA , thus allowing both strand to be replicated.

Telomerase is an enzyme which is responsible for maintaining the length of the chromosomes. Telomerase is a ribonucleoprotein ,it adds telomere repeat sequence at the 3' end of telomere during replication. Telomere is the repetitive nucleotide sequences found at the end of chromosomes. It protects the chromosome from shortening and fusion with other chromosomes.

So without Telomerase the chromosomes would progressively shorten with each replication.
