Question

Adenine can pair with which of the following nitrogenous bases? (a) Guanine (b) Uracil (c) Thymine (d) Both (b) and (c)

Answer 1

Answer:

Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs. Adenine forms two hydrogen bonds with thymine in DNA and two hydrogen bonds with uracil in RNA, while three hydrogen bonds are formed between guanine and cytosine.

Answer 2

Adenine can pair with Uracil and Thymine. (Option D)

• Adenine is a type of chemical compound that is used to make one of the building blocks of DNA and RNA.
• Thymine carries the instructions needed to assemble a protein.
• All DNA built by Adenine have their shape and size and are supposed to fit together in just the right way.
• All the nitrogenous bases are joined to each other by weak hydrogen bonds, these bonds help them turn mild.
