Lab 2 - Ex. 7

A human diploid has _____ chromosomes?

46

Prohpase

Chromosomes condense Nuclear envelope disappears Spindle apparatus forms

Metaphase

Chromosomes line up in the middle of the cell

Cytokinesis

Division of the cytoplasm during cell division

A karyotype is used to count centrioles and spindle fibers?

False

How are the daughter cells similar?

Have identical chromosomes

What's the difference between cytokinesis and mitosis?

Mitosis divides the nucleus, cytokinesis divides the cytoplasm.

Telophase

Nuclear envelope forms around the two daughter cells, chromosomes condense and spindle disappears

Anaphase

Spindle fibers pull the sister chromatids apart, to opposite poles of cell.

G1 phase

The first gap phase, when cell growth occurs and cytoplasmic organelles duplicate.

G2 phase

The second growth phase , when cell growth occurs and cytoplasmic organelles duplicate.

Daughter cells are formed from cell cycles

True

sister chromatids separate to opposite poles during ?

anaphase

a cell in the stage of Gzero

ceases cell division

S1 phase

chromosomes are repilcated and the synthesis of DNA molecules takes place

which of the following occurs in prophase?

chromosomes condense

In animal cells, the indentation where the cells are pinching apart during telophase is called?

cleavage furrow

which of the following events occurs during telophase?

cytokineses

which of the following is not apart of interphase?

cytokinesis

which is the correct sequence of the M (mitotic) phase?

prophase, metaphase, anaphase, telophase
