Question

Which is NOT the function of eukaryotic alpha DNA polymerase?

a Tethers primase to catalytic subunit A
b Makes RNA primer
c Replicates DNA
d Extends RNA primer by making short DNA (iDNA)

Answer 1

Eukaryotic alpha DNA polymerase does not make RNA primers; this is the function of primase.

Step-by-step explanation:

The function that is NOT associated with eukaryotic alpha DNA polymerase is "b Makes RNA primer". This task is instead carried out by an enzyme known as primase. Alpha DNA polymerase's functions include tethering primase to catalytic subunit A, replicating DNA, and extending an RNA primer by making short DNA, sometimes referred to as iDNA (initiator DNA). In contrast, primase's role is to synthesize a short RNA primer which is later extended by DNA polymerases during DNA replication.
