Question

The sequence of the mRNA transcribed by the given segment of DNA will be -

$5^{\prime }\overline{ATGTCCTTGCAACAT{3}^{\prime }}$ - sense strand

$3^{\prime }\overline{TACAGGAACGTTGTA{5}^{\prime }}$

• A. 5' AUGUCCUUGCAACAU 3'
• B. 5' UACAACGUUCCUGAU 3'
• C. 5' UACAGGAACGUuGTA 3'
• D. 5' AUGUUGCAAGGACAU 3'

Answer 1

The correct option is A 5' AUGUCCUUGCAACAU 3'

Sense strand is the coding strand of the DNA. Antisense strand is the template strand. It has complementary sequence of the sense strand. The antisense strand is transcribed to make mRNA strand. The sequence of the mRNA strand is same as sequence of mRNA in which T's are replaced by U's.

Hence, the sequence of the mRNA transcribed by the given segment of DNA will be 5' AUGUCCUUGCAACAU 3'.

Thus, the correct answer is '5' AUGUCCUUGCAACAU 3'.
