Question

Select the correct answer from each drop-down menu.

RNA primase synthesizes RNA primer that attaches itself at the initiation point of replication.

RNA primer constructed during DNA replication needs to be replaced because RNA differs from DNA. It contains instead of .

Answer 1

It contains Uracil (U) instead of Thymine (T).

Step-by-step explanation:

ah

Answer 2

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Step-by-step explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).
