Give a reason for the discontinuous synthesis of DNA on one of the parental strands? long
Answers
During the process of replication of DNA, each of the parental DNA strands is used as a template. The strand which is elongating from the template in 3'→5' direction will grow continuously but the strand which is growing from template having polarity 5'→3' will grow discontinuously because RNA primer will be formed at 5' end only so discontinuous strand will require many RNA primer and strand will be synthesised in small segments or Okazaki segments.
( dude you can just ask questions on internet, you will get it easily)
Answer:
Synthesis of DNA always takes place in 5' 3'direction. ... That is why DNA synthesis is discontinuous on one of the parental strands of DNA. These small stretches called Okazaki fragments are joined together by DNA ligase enzyme that closes the nicks.
