Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What are the complementary base pairs in DNA?

Back

A pairs with T, and C pairs with G.

Front

What is the S phase in the cell cycle?

Back

The phase where DNA replication occurs, preparing the cell for division.

Front

What is a nucleotide?

Front

What is a chromatid?

Back

One half of a duplicated chromosome, which is joined to the other half by a centromere.

What is a chromosome?

Back

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

Front

What is the cell cycle?

Back

The series of events that take place in a cell leading to its division and replication.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA into proteins.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is chromatin?

Back
