Solution
During DNA replication, DNA is read in the upstream (3’→5’) direction on the template strand and synthesized in the downstream (5’→3’) direction on the daughter strand.
Here's a step-by-step explanation:
- The process begins at specific locations in the genome called origins.
- The two DNA strands are separated by an enzyme called DNA helicase, which breaks the hydrogen bonds between the base pairs.
- The point where the DNA is opened up, and the two strands are separated is called the replication fork.
- DNA polymerase is the enzyme responsible for reading the template strand and synthesizing the new daughter strand.
- DNA polymerase can only add nucleotides to the 3' end of a DNA strand. Therefore, it reads the template strand in the 3' to 5' direction and synthesizes the new daughter strand in the 5' to 3' direction.
- This process continues until the entire molecule is copied.
