DNA and RNA

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What sugar is found in RNA?

Back

RNA contains the sugar ribose.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

Who are the scientists credited with the discovery of the double helix structure of DNA?

Back

James Watson and Francis Crick.

Front

What is the difference between DNA and RNA in terms of sugar?

Back

DNA contains deoxyribose, while RNA contains ribose.

Front

What is base pairing in DNA?

Back

Base pairing refers to the specific pairing of nitrogenous bases: adenine with thymine, and cytosine with guanine.

Front

What is a nucleotide composed of?

Back

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

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and provides instructions for protein synthesis.

Front

What is the function of RNA?

Back

RNA plays a crucial role in translating the genetic information from DNA into proteins.

Front

What is the difference between purines and pyrimidines?

Back

Purines (adenine and guanine) have a double-ring structure, while pyrimidines (cytosine, thymine, and uracil) have a single-ring structure.
