Below is a partial DNA sequence used to answer the following questions.

5' - TATGCAGCACATT - 3' 3' - ATACGTCGTGTAA - 5'

If transcription occurred from left to right, which strand is the template strand?

a. 3' - TATGCAGCACATT - 5'
b. 5' - TATGCAGCACATT - 3'
c. 5' - ATACGTCGTGTAA - 3'
d. 3' - ATACGTCGTGTAA - 5'

Respuesta :

Answer:

d. 3' - ATACGTCGTGTAA - 5'

Explanation:

The template strand refers to the strand in which the mRNA is developed in the DNA strand as it involves the transcription for template

In the given situation, since there is a partial DNA sequence mentioned plus it the transcription has also occurred from left position to the right position i.e

5' - TATGCAGCACATT - 3'

So it would be

3' - ATACGTCGTGTAA - 5'

Hence, the correct option is d.
