Front

What happens during the process of differentiation?

Back

Only specific sections of DNA sequence are activated to determine the structure and functions of a body cell.

Front

Front

What is DNA?

Back

Deoxyribonucleic acid, the molecule that carries genetic information.

Front

What is the role of the nitrogenous base in nucleotides?

Back

It determines the genetic code by pairing with complementary bases.

Front

What is the function of DNA replication?

Back

To ensure that each new cell receives an exact copy of the DNA.

Front

What is the significance of the cell cycle?

Back

It regulates cell growth, DNA replication, and cell division.

Front

What are the four main phases of the cell cycle?

Back

G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).
