Which of the following proteins is responsible for synthesizing RNA primers?
A
Topoisomerases
B
Single-stranded binding proteins
C
Primase
D
DNA polymerase III

1
Understand the role of RNA primers in DNA replication: RNA primers are short sequences of RNA that provide a starting point for DNA synthesis.
Identify the function of each protein listed: Topoisomerases relieve the tension in the DNA helix, single-stranded binding proteins stabilize the unwound DNA, and DNA polymerase III extends the DNA strand from the RNA primer.
Recognize that the synthesis of RNA primers is a specific task that requires a particular enzyme.
Recall that Primase is the enzyme responsible for synthesizing short RNA sequences called primers, which are necessary for DNA polymerase to begin DNA synthesis.
Conclude that among the options provided, Primase is the correct protein responsible for synthesizing RNA primers during DNA replication.
