If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence?
View answer and explanation
Correct option: A
UAGAC
Option A (UAGAC) is correct because in RNA, Adenine pairs with Uracil, Thymine is replaced by Uracil, Cytosine pairs with Guanine, and Guanine pairs with Cytosine. The complementary sequence is created by replacing each base with its pair.
