The following solution is suggested to handle the subject “Which of the following statements in NOT true about DNA replication? DNA replication involves synthesis of…“. Let’s keep an eye on the content below!
Question “Which of the following statements in NOT true about DNA replication? DNA replication involves synthesis of…”
Answer
Living organisms use A) RNA primes to initiate the process of creating a new strand of DNA. This method, unlike the leading strand, results in repeated starting and stopping DNA synthesis. It requires multiple RNA
primers.
B) DNA ligase is an enzyme which repairs breaks or irregularities in the backbone double-stranded DNA molecules. It is vital in role DNA repair and DNA replication. DNA ligase
functions is formed by the formation of a bond between the ends of “donor” and “acceptor” nucleotides.
C) DNA polymerase I synthesizes Okazaki fragments until they reach the previous RNA primer. Next, the enzyme acts simultaneously as a 5’-3’ exonuclease. It removes primer ribonucleotides in the front and adds deoxyribonucleotides to the back. The region is then replaced with DNA.
D) DNA runs in 5′-3′ directions. DNA polymerase cannot adds bases in the 3’-5’ direction to the template strand. DNA is synthesized “backward” in short fragments that move away from the replication fork. These are known as Okazaki fragments.
Therefore, last option is NOT true.
Conclusion
Above is the solution for “Which of the following statements in NOT true about DNA replication? DNA replication involves synthesis of…“. We hope that you find a good answer and gain the knowledge about this topic of science.
