Q. If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence?
(a) TTAGU
(b) UAGAC
(c) AACTG
(d) ATCGU
Solution :
Correct option : B Pairing in strands follows the pairing principle. That is A with U and C with G. The given sequence on DNA strand is as follows: ATCTG. thus, the complementary one on RNA will be: UAGAC.
