Type of RNA that is used to start process of replication in prokaryotic cell:
Correct answer: D. RNA Primers
- A. tRNA
- B. rRNA
- C. mRNA
- D. RNA Primers
Explanation
Option D is correct. The type of RNA that initiates the process of replication in prokaryotic cells is RNA primase, which synthesizes short RNA primers. These primers are crucial because they provide a free 3' hydroxyl group for DNA polymerase to extend and synthesize new DNA strands. In contrast, tRNA, mRNA, and rRNA serve different functions: tRNA delivers amino acids for protein construction, mRNA carries genetic information for protein synthesis, and rRNA is a structural component of ribosomes. Therefore, they do not play a role in the initiation of DNA replication, making them incorrect choices.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
