Question
Which enzyme is responsible for adding complementary DNA bases to an exposed DNA strand?
Solution
The enzyme responsible for adding complementary DNA bases to an exposed DNA strand is DNA polymerase.
Here are the steps of how it works:
-
The process begins with the unwinding of the double-stranded DNA. This is done by an enzyme called DNA helicase, which breaks the hydrogen bonds between the base pairs, resulting in the formation of a 'replication fork' that is essentially an area of separated strands of DNA.
-
Once the DNA strands are separated, DNA polymerase can start its work. It moves along the exposed DNA strand and reads the bases.
-
As it reads the bases, it adds complementary bases to the strand. This means that if it reads an adenine (A), it will add a thymine (T) to the new strand. If it reads a cytosine (C), it will add a guanine (G), and so on.
-
This process continues until the entire DNA molecule has been replicated. The result is two identical DNA molecules, each consisting of one original and one new strand.
So, in summary, the enzyme responsible for adding complementary DNA bases to an exposed DNA strand
