Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. i-d, ii-c, iii-b, iv-a.
- Helicase is an essential enzyme in DNA replication and repair processes that plays a crucial role in unwinding the DNA double helix.
- RNA primase is a crucial enzyme in DNA replication that synthesizes RNA primers, which are short RNA sequences complementary to a single-stranded DNA template.
- DNA polymerase is a crucial enzyme involved in the process of DNA replication and repair. It is responsible for the polymerization of nucleotides to form a new DNA strand, complementary to a template strand.
- DNA ligase is an essential enzyme in DNA replication and repair that plays a critical role in joining DNA fragments. It catalyzes the formation of a phosphodiester bond between the 3' hydroxyl end of one DNA fragment and the 5' phosphate end of another, thus creating a continuous DNA strand.
