Question

If the coding strand have the sequences 5'-AGGCCT-3' then find out the sequence in the strand of mRNA transcribed.

• A. 5'-AGGCCU-3'
• B. 3'-AGGCCU-5'
• C. 3'-UCCGGA -5'
• D. 5'-ACCGGU-3'

Answer 1

The correct option is A 5'-AGGCCU-3'

• The sequence of mRNA is same as the coding strand of DNA.
• In the transcribed RNA, thymine is replaced by uracil.
• Therefore, the sequence of mRNA will be-

5’ -AGGCCU-3’
