Mitosis

A

10

According to cell theory, what is the basic unit of life?

Cells are the basic unit of life

10

What does cell theory say about where cells come from?

All cells come from a pre-existing cell - not spontaneous 

10

What are all living things made of?

Cells

10

What is mitosis?

The process of dividing 1 cell into 2 daughter cells

10

What is happening during interphase?

The cell is resting & doing normal cell functions

B

10

____________ is DNA that is loose and accessible 

Chromatin

10

What is happening during synthesis?

The DNA is replicating (making a copy of itself)

10

How is cytokinesis different from mitosis?

The cytoplasm divides completely in cytokinesis

Mitosis is the division of the nucleus 

10

When the rest of the cell divides, it is not part of mitosis, and the individual chromosomes are not visible

Cytokinesis 

10

Half of a replicated chromosome

Sister chromatids

chromatids

C

10

When do we stop at checkpoints during the cell cycle? 

Between G1 and S

Between S and G2 

Between G2 and mitosis 

10

What does the acronym PMAT stand for?

Prophase

Metaphase

Anaphase

Telophase

10

What is the purpose of mitosis?

Growth and Repair

10

Define apoptosis

Programmed cell death

10

What happens during anaphase?

The chromosomes are pulled APART into chromatids

D

10

What happens during telophase?

Chromatids finish moving apart and the nucleus reforms

10

What happens during prophase?

The cell is PREPARING to divide, the nuclear membrane dissolves and DNA condenses into chromosomes

10

What happens during metaphase?

The chromosomes MOVE toward the middle 

10

Mitosis is what we call cell division in eukaryotes.

What is cell division called in bacteria?

Binary Fission

10

What happens to the nuclear membrane during prophase and why is this important for mitosis?

It dissolves

E

10

Which cells in the body are capable of self-renewal and differentiation into specialized cell types?

Stem cell

10

If the following represents chromosomes. 

How many chromatids are there?

X    X    X

6

10

What is the key factor that determines the fate of a cell during differentiation?

Gene expression

10

How does the environment surrounding a cell influence its differentiation process?

Signals from neighboring cells, such as growth factors and chemical cues, guide differentiation.

10

Which process is responsible for creating specialized cells such as muscle cells, nerve cells, and blood cells from stem cells?

Cell differentiation
