Front

What is a plasmid?

Back

A plasmid is a small, circular piece of DNA that can carry one or more genes into a cell.

Front

What is the function of histones in eukaryotic cells?

Back

Histones package and regulate DNA, allowing for proper organization and expression.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is translation?
