Question

If the sequence of the coding strand in a transcription unit is written as follows: 5'-atgcatgcatgcatgcatgcatgcatgc-3' write down the sequence of mrna.

Answer 1

Answer:

The correct answer 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’
