RNA and Transcription

Front

What are introns in RNA?

Back

Introns are sections of the RNA molecule that are not involved in the making of protein and are removed during RNA processing.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during transcription.

Front

What type of sugar is found in RNA?

Back

Ribose is the sugar found in RNA.

Front

What is a mutation?

Back

A mutation is a change in the base sequences of DNA.

Front

What enzyme is responsible for filling in gaps with new nucleotides during DNA replication?

Back

DNA polymerase fills in gaps with new nucleotides during DNA replication.

Front

What are exons in RNA?

Back

Exons are sections of the RNA molecule that are involved in the making of protein and are retained after RNA processing.

Front

What might cause accidental damage to existing DNA?

Back

Exposure to chemicals, radioactivity, X-rays, and excessive exposure to ultraviolet light can all cause damage to existing DNA.

Front

What is the process of transcription?

Back

Transcription is the process by which RNA is synthesized from a DNA template.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication.
