Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A strand of DNA has these bases:AGC CAT GTA TAC What is the complementary DNA strand?
A
ACG GAT CTA TAG
B
TCG GTA CAT ATG
C
TGC CTA GAT ATC
D
UCG CUA CAU AUG
Explanation: 

Detailed explanation-1: -Based on complementary base pairing rules, T pairs with A, whereas C pairs with G. Hence, the complementary sequence for 3’ ATGGCT 5’ starting from the 5’ end is 5’ TACCGA 3’.

Detailed explanation-2: -In the complementary strand of DNA, the bases that bind to TAC are complimentary, thus they are ATG.
