During the process of DNA replication, primase uses the following DNA sequence as a template to make a primer: 5'-GATTCAAGTAGTC-3' Which of the following is the correct primer sequence synthesized using this template?

Respuesta :

The question is incomplete as it lacks the options which are:

a. 5'-GAUUCAAGUAGUC-3'

b. 5'-CUAAGUUCAUCAG-3'

c. 5'-GACUACUUGAAUC-3'

d. 5'-CTAAGTTCATCAG-3'

Answer:

The correct answer will be -5'-CTAAGTTCATCAG-3'

Explanation:

A primer is a short sequence made of few nucleotides which help in the initiation of the DNA replication process. The process of DNA replication begins only when the DNA polymerase enzyme binds the primer.

The sequence of nitrogenous bases in the primer is complementary of the template bases in which A binds T and G binds C.

Since in the given question,  

the template segment of DNA is- 5'-GATTCAAGTAGTC-3'  

Therefore according to the rule of base pairing

The primer sequence will be-  5'-CTAAGTTCATCAG-3'.

Thus, 5'-CTAAGTTCATCAG-3' is the correct answer.
