Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During DNA replication, what would be the complementary strand to the original DNA segment of GCTAAT?
A
CGATTA
B
GGATTAC
C
GGAUUA
D
GGUTTU
Explanation: 

Detailed explanation-1: -During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand.

Detailed explanation-2: -If half of the DNA molecule is given as ACG-TCC-GTA then the complementary strand to that will be b. TGC-AGG-CAT. The base pairing of DNA is formed based on the complementarity base pairing. Therefore Adenine pairs with Thymine and Cytosine pairs with Guanine.

Detailed explanation-3: -ATGGCTTGA…. 5’? Explanation: The complementary of A is T and for G is C, therefore the complementary sequence should be …. TACCGAACT….
