Question

One strand of DNA molecule contains the base sequence AGT. What is the base sequence on the other strand of the DNA molecule?
a) AGT
b) GAT
c) TAC
d) TCA​

Answer 1

Answer:

I think so it should be GAT

Answer 2

One strand of DNA molecule contains the base sequence AGT. The base sequence on the other strand of the DNA molecule is TCA (Option d)

• The structure of a DNA molecule consists of two strands woven into each other and held together by certain bonds.
• Both the strands are complementary to each other.
• There are four nitrogenous bases, Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).
• A always binds with T by two bonds and G always binds with C by three bonds.
• So, if the sequence of one strand is given, the sequence of the complementary strand can be determined.
