Chapter 10 Review

The structure labeled A (above) is called the ________. The structures labeled B are called ____________.The whole structure pictured is called a __________.

centromere, sister chromatids,replicated chromosome

Cyclins are a family of closely related proteins that

regulate the cell cycle in eukaryotic cells.

Cancer is a disorder in which some cells have lost the ability to control their

growth rate

A cell with a defective p53 gene is likely to

have chromosomal damage

During metaphase, each chromosome is connected to a (an) _________ at its centromere.

spindle fiber

The process by which a cell divides into two daughter cells is called

cell division.

One difference between cell division in plant cells and in animal cells is that plant cells have a _________ while animal cells have a _________.

cell plate, cleavage furrow.

The cell cycle is?

a series of events that cells go through as they grow and divide.

List the phases of mitosis in their proper sequence.

a. Prophase b. Metaphase c. Anaphase d.Telophase

The two main stages of cell division are called

a. mitosis b .cytokinesis

Compared to small cells, large cells have more trouble

moving needed materials in and waste products out of the cell

When during the cell cycle are chromosomes visible?

only during cell division

Cancer cells form masses of cells called

tumors

A cell that has 10 chromosomes in the G1 phase will have___ chromatids in the G2 phase.

20

During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?

Metaphase

Together, the G1 phase, S phase, and G2 phase are called

Interphase

During normal mitotic cell division a parent cell having eight chromosomes will produce two daughter cells, each containing

8 chromosomes

Which events occur during interphase?

G1: size of cell increases, S: duplicates chromosomes and synthesis of DNA, G2:organelles are produced

During which phase(s) of mitosis are structures like the one shown above visible?

Prophase and Metaphase

When during the cell cycle is a cell's DNA replicated?

S phase of Interphase

As a cell becomes larger, what happens to the volume and the surface area?

The volume increases faster than the surface area.

What is the role of the spindle during mitosis?

They help to organize and separate chromosomes

If the length of a cell increases 4 times, its volume increases about

X or 4 = 64

What happens when cells come into contact with other cells?

they stop dividing
