Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and the mitotic phase (M).

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life, serving as the blueprint for traits of all living organisms.

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that have the potential to develop into different cell types in the body.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, often influenced by genetic and environmental factors.

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions while preparing for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, the cell replicates its DNA, resulting in two identical sets of chromosomes.

Front

What is the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell continues to grow and prepares for mitosis.

Front

What is the M phase?

Back

The M phase is the mitotic phase of the cell cycle where the cell divides into two daughter cells.

Front

Why is DNA important for living organisms?

Back

DNA serves as the blueprint for traits of all living things, determining characteristics and functions.

Front

What role do ribosomes play in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into proteins.
