DNA and RNA

Front

What are nucleotides made up of?

Back

Nucleotides consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What shape does a DNA molecule have?

Back

A DNA molecule has a double helix shape.

Front

What is the sugar found in RNA?

Back

The sugar found in RNA is ribose.

Front

What is a key difference between DNA and RNA regarding their sugars?

Back

DNA contains deoxyribose, while RNA contains ribose.

Front

What nitrogenous base is found in DNA but not in RNA?

Back

Thymine is found in DNA but not in RNA; RNA contains uracil instead.

Front

What is the primary function of DNA?

Back

DNA serves as the blueprint for the traits of all living things.

Front

What is the role of RNA in protein synthesis?

Back

RNA acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

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.

Front

How does the structure of RNA differ from DNA?

Back

RNA is usually single-stranded, while DNA is double-stranded.
