At what point during normal DNA replication is genetic material lost from the telomeres?
  • a)
    Enzymatic action of telomerase
  • b)
    “Unzipping” by DNA helicase
  • c)
    Attachment of DNA polymerase to the leading strand
  • d)
    Joining of adjacent Okazaki fragments
Correct answer is option 'D'. Can you explain this answer?

At what point during normal DNA replication is genetic material lost f...
Telomeres are repetitive DNA sequences found at the ends of chromosomes. During DNA replication, the lagging strand is synthesized discontinuously in short fragments called Okazaki fragments. These fragments are then joined together by the enzyme DNA ligase. However, because the lagging strand synthesis starts away from the telomeres, a small portion of the telomeric DNA is not replicated during each round of DNA replication.
Over time, this loss of genetic material from the telomeres can lead to the shortening of the chromosomes. Telomerase, an enzyme that contains its own RNA template, can counteract this shortening by adding repetitive DNA sequences to the telomeres. This occurs during the enzymatic action of telomerase, which extends the telomeric DNA and maintains its length. However, telomerase activity is not present in all cell types and is particularly active in stem cells and certain cancer cells.
Therefore, while telomerase can help to counteract the loss of genetic material from telomeres, the actual loss occurs during the joining of adjacent Okazaki fragments.
