Question

Choose the correct answer from the alternatives given :
If the sequence of nitrogen bases of the coding strand of DNA in a transcription unit is: 5 - A T G A AT G - 3, the sequence of bases in its RNA transcript would be

• A. 5-AUGAAUG-3
• B. 5-UACUUAC-3
• C. 5 CAUUCAU 3
• D. 5-GUAAGUA-3.

Answer 1

The correct option is A 5-AUGAAUG-3

• Translation is the process of conversion of DNA into RNA.
  
• It includes coding and template strands of DNA in which template strand forms the RNA and follows the base pairing rule except for uracil in place of thymine in RNA strand.
• In the question,

We have coding strand-ATGAATG
So, template strand-TACTTAC

Therefore, RNA strand-AUGAAUG

So the correct option is '5-AUGAAUG-3'.
