What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein or set of proteins.

Front

What is the role of nitrogen bases in DNA?

Back

Nitrogen bases in DNA store genetic information and determine the traits of an organism through their sequences.

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 replication in the context of DNA?

Back

Replication is the process by which DNA makes a copy of itself before cell division.
