Before a parent cell splits into two it must _______________________________________ so that it can ______________________________.

Back 3

Duplicate its chromosomes so that it can distribute one set of DNA to each of its daughter cells.

Front 4

What is a chromosome?

Back 4

The main gene carrying structure of a prokaryotic cell.

Front 5

Front 6

What is asexual reproduction?

Back 6

The creation of genetically identical offspring by a single parent without the participation of gametes.

Back 7

Mitosis

Front 8

What is sexual reproduction?

Back 8

The creation of genetically distinct offspring by the fusion of two haploid gametes, forming a diploid zygote.

Front 9

Name the type of cell division in sexually reproducing organisms that is responsible for
Growth and maintenance_________________
Reproduction ___________________

Back 9

Growth and maintenance = mitosis

Reproduction = meiosis

Front 10

What is the material chromosomes are made up of? What is this material made up of?

Back 10

Chromatin, which is made up of DNA and proteins.

Front 11

At what point in a cell cycle can you see chromosomes under a light microscope?

Back 11

When the cell is dividing.

Front 12

What feature allows long molecules of DNA to fit into the tiny nucleus?

Back 12

DNA is coiled.

Front 13

Define the cell cycle

Back 13

The ordered sequence of events that extends from the time a cell is first formed from a dividing parent cell until its own division into two cells.

Front 14

In the eukaryotic cell cell cycle the cell spends most of its time in _______________ about ___% to be exact. This is a time where the cell _______________________ such as _____________ and _____________. State two other things that happen during interphase.

Back 14

In the eukaryotic cell cell cycle the cell spends most of its time in interphase about 90% to be exact. This is a time where the cell preforms its normal functions within the organism such as growth and and metabolism.
Cell doubles everything in its cytoplasm

Cell grows in size

Front 15

A duplicated chromosome consists of two sister ________ joined together at the ________.

Back 15

Chromatids
Centromere

Front 16

What is the most important event that takes place during interphase? What stage does this occur in? What does the letter stand for

Back 16

Chromosome duplication occuring in the S Phase. S stands for synthesis

Front 17

During the G2 phase _____________________________________________.

Back 17

The cell consists of two identical sister chromatids and the cell is preparing to divide.

Front 18

The Mitotic M phase includes two stages. _________________ and ____________. It is the part of the cell cycle where _________________

Back 18

Mitosis and cytokenesis
The cell is actually dividing

Front 19

In the eukaryotic cell cycle during mitosis what is happpening.

Back 19

the nucleus and all its contents (DUPLICATED CHROMOSOMES) divide and are evenly distributed forming two daughter nuclei.

Front 20

In the eukaryotic cell cycle during cytokenesis what is happening.

Back 20

the cytoplasm is divided in two

Front 21

What are the two broadest divisions of the cell cycle? What two processes are involved in the actual duplication of the cell?

Back 21

Interphase and mitotic m phase.
Mitosis and cytokenesis.

Front 22

Describe the series of events that occur during mitosis including the cellular events and structural changes that occur during them.

Back 22

1. Chromatin fibres coil, spindle forms, nuclear envelope breaks into pieces.
2. Chromosomes move towards center of the cell.

3. Centromeres line up

4. Sister chromatids seperate

5. Nuclear envelope forms, chromosomes uncoil and spindle dissapears.
