Question

 If the sequence of a coding strand in a transcription unit is written as follows:
5'-ATGCATGCATGCATGCATGCATGCATGC-3'
Write down the sequence of m-RNA.​

Answer 1

Explanation:

Hello...

◆ Answer -

5’ − AUGCAUGCAUGCAUGCAUGCAUGCAUGC - 3’

● Explaination -

Given is the sequence of coding strand -

5' - ATGCATGCATGCATGCATGCATGCATGC - 3'

We know that m-RNA formed is complimentary to template strand which itself is complimentary to coding strand.

Simply told, sequence of m-RNA strand is same as that of coding strand except T (Thymine) is replaced by U (Uracil).

Therefore, sequence of m-RNA formed is -

5’ − AUGCAUGCAUGCAUGCAUGCAUGCAUGC - 3’

Answer 2

Answer:

If the coding strand in a transcription unit is

5’− ATGCATGCATGCATGCATGCATGCATGC-3’

Then, the template strand in 3’ to 5’ direction would be

3’ − TACGTACGTACGTACGTACGTACGTACG-5’

It is known that the sequence of mRNA is same as the coding strand of DNA.

However, in RNA, thymine is replaced by uracil.

Hence, the sequence of mRNA will be

5’ − AUGCAUGCAUGCAUGCAUGCAUGCAUGC-3’
