Back

Crossing over increases genetic diversity by exchanging genetic material between homologous chromosomes.

Front

What happens to the chromosome number during meiosis?

Back

The chromosome number is reduced by half during meiosis.

Front

What is the goal of molecular cloning?

Back

The goal of molecular cloning is to insert DNA into bacteria to create more plasmids, known as recombinant DNA.

Front

What is transcription?

Back

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

Front

What is the role of RNA in protein synthesis?
