Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many hydrogen bonds form between Adenine and Thymine?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds.

Detailed explanation-2: -It is a truth universally acknowledged that a guanine–cytosine (GC) base pair has three hydrogen bonds whereas adenine–thymine (AT) has two.

Detailed explanation-3: -Answer and Explanation: The number of specific bases is determined by the number of hydrogen bonds each base pair can make. Adenine pairs with thymine in DNA or uracil in RNA. Adenine creates two hydrogen bones with either thymine or uracil because it has two nitrogen atoms in its ring that can form hydrogen bonds.

Detailed explanation-4: -There are two hydrogen bonds between A and T while three hydrogen bonds between Guanine (G) and Cytosine (C).

Detailed explanation-5: -Adenine-uracil base pairs, or AU base pairs, are held together by 2 hydrogen bonds. Guanine-cytosine base pairs, or GC base pairs, are held together by 3 hydrogen bonds.
