Question

NEED HELP ASAP!!!!

The process of DNA replication requires the
help of several enzymes.
What does the enzyme DNA telomerase do
during the process of DNA replication?
A. Proofreads the nitrogenous bases
B. unwinds the DNA helix at the start of replication
C. Adds a tail to the DNA strand at the end of replication

Answer 1

Answer: B

Explanation: I do apologise if I got this wrong

extends the ends by copying the RNA template and extending one end of the chromosome. DNA polymerase can then extend the DNA using the primer. In this way, the ends of the chromosomes are protected. and or One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
