Front

What is the structure of a nucleotide?

Back

A nucleotide is composed of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What type of bond holds the base pairs together in DNA?

Back

Hydrogen bonds hold the base pairs together in DNA.

Front

What is the role of deoxyribose in DNA?

Back

Deoxyribose is the sugar component of DNA nucleotides, forming part of the backbone.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is the significance of base pairing in DNA?

Back

Base pairing ensures accurate replication of DNA and the transmission of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is the function of the phosphate group in a nucleotide?

Back

The phosphate group links nucleotides together, forming the backbone of the DNA strand.

Front

What is the complementary base pair for Cytosine?

Back

Guanine is the complementary base pair for Cytosine.
