Question 3 (1 point)
During DNA replication, one of the new strands of DNA is synthesized continuously.
The other strand is synthesized as a number of separate fragments of DNA that are
subsequently linked by DNA ligase. Why does this occur?
- RNA primers only anneal to one of the parental strands of DNA.
- DNA polymerase III only synthesizes DNA in the 3' - 5' direction.
- DNA polymerase III only synthesizes DNA in the 5'-3' direction.
- One of the parental strands is unwound slower than the other by helicase.
