Front

What is DNA replication?

Back

The process by which a DNA molecule makes a copy of itself.

Front

What does semiconservative replication mean?

Back

It means that each new DNA molecule consists of one original strand and one new strand.

Front

What are gametes?

Back

Reproductive cells (sperm and eggs) that carry genetic information to offspring.

Front

What is the role of mutations in genetics?

Back

Mutations are changes in the DNA sequence that can lead to variations in traits.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing gametes.

Front

What occurs during Prophase I of meiosis?

Back

Homologous chromosomes pair up and exchange genetic material through crossing over.

Front

What is the difference between somatic cells and gametes?

Back

Somatic cells are body cells, while gametes are reproductive cells.

Front

What is a chromosome?

Back

A structure made of DNA and proteins that contains genetic information.

Front

What is the significance of DNA in genetics?

Back

DNA carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms.

Front

What is a mutation?

Back

A permanent alteration in the DNA sequence that makes up a gene.
