How many chromosomes do human cells have?

46

What happens during the cell cycle?

A cell grows, prepare for division, and divides to form two daughter cells, each of which then begins the cycle again

G1 phase?

A period of activity in which cells do most of their growing

S phase

Chromosomes are replicated and the synthesis of DNA molecules take place

How is genetic information passed on in eukaryotic cells?

It's carried by chromosomes

Centromeres

Located near the middle of the chromatids nd each human chromosomes consist of 2 chromatids

What are chromosomes?

Made up of DNA and carries the cell's coded genetic information and proteins.

G2 phase

Shortest of the three phase of interphase. Many of the organelles and molecules required for cell division are produced.

What happens during mitosis?

The division of the cell nucleus and cytokinesis take place

Chromatids?

Two identical sister

Is interphase long? How many phase is it divided into?

Yes. G1, S, and G2
