Question

select the correct answer.
an enzyme in a cell became dysfunctional because of an alteration. as a result, the dna strands would not separate to begin the replication process.
which enzyme has been affected?
a. dna ligase
b. dna polymerase
c. helicase
d. rna primase
e. topoisomerase

Explanation:

Helicase is the enzyme responsible for unwinding and separating the DNA strands at the beginning of DNA replication. If it is dysfunctional, the strands cannot separate to start the replication process. DNA ligase joins DNA fragments, DNA polymerase synthesizes new DNA strands, RNA primase makes RNA primers, and topoisomerase relieves supercoiling.

Answer:

C. helicase
