Which of the following activity is associated with Klenow fragment?
Understand the Problem
The question is asking which specific activity is associated with the Klenow fragment among four options related to nuclease and polymerase activities.
Answer
Polymerase activity.
The activity associated with the Klenow fragment is Polymerase activity.
Answer for screen readers
The activity associated with the Klenow fragment is Polymerase activity.
More Information
The Klenow fragment lacks the 5′-3′ exonuclease activity but retains the 5′-3′ polymerase and 3′-5′ exonuclease (proofreading) activities.
Tips
Confusing exonuclease and polymerase activities is common. Remember, polymerase activity involves synthesizing DNA, whereas exonuclease activity involves removing nucleotides.
