Front

What is the role of anaphase in cell division?

Back

Anaphase is the stage of cell division where chromosomes are pulled apart to opposite poles of the cell.

Front

What happens during metaphase in the cell cycle?

Back

During metaphase, chromosomes line up along the equatorial plane of the cell.

Front

What is prophase in the context of cell division?

Back

Prophase is the stage where chromosomes become more tightly coiled and the nuclear envelope begins to break down.

Front

What is the main difference between embryonic stem cells and adult stem cells?

Back

Embryonic stem cells can differentiate into more cell types than adult stem cells.

Front

How does the surface area to volume ratio affect cell size?

Back

A higher surface area to volume ratio increases the rate of exchange of materials with the environment, limiting cell size.

Front

What is the primary function of tRNA in protein synthesis?

Back

The primary function of tRNA is to bring amino acids from the cytoplasm to the ribosomes for protein synthesis.

Front

What is the correct order of the cell cycle starting from Gap 1?

Back

G1 > S > G2 > M.

Front

Define the term 'cell cycle'.

Back

The cell cycle is the series of phases that a cell goes through to divide and replicate.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.

Front

What is the significance of the G2 phase in the cell cycle?

Back

The G2 phase is important for cell growth and preparation for mitosis.
