Question
Which enzyme is responsible for replacing the RNA nucleotides with DNA nucleotides?
Solution
The enzyme responsible for replacing the RNA nucleotides with DNA nucleotides is called DNA polymerase. Here are the steps:
-
The process begins with the unwinding of the DNA double helix by the enzyme helicase. This creates a replication fork where DNA replication occurs.
-
An enzyme called primase synthesizes a short RNA primer on each template strand to provide a starting point for DNA synthesis.
-
DNA polymerase then binds to the site of the primer. This enzyme is responsible for adding new DNA nucleotides that are complementary to the template strand.
-
As DNA polymerase moves along the template strand, it replaces the RNA primer with DNA nucleotides.
-
The end result is two identical copies of the original DNA molecule, each composed of one old (conserved) strand and one new strand.
