The DNA strand unwinds |
1st |
|
|
The DNA strand unzips |
2nd |
|
|
The nitrogen bases floating in the nucleus attach to their pair |
3rd |
|
|
The DNA becomes two exact strands |
4th |
|
|
Name the stage of the cell cycle. |
|
|
|
In this stage the cell prepares for division by producing structures it needs. |
Interphase |
|
|
This stage takes the most time. |
Interphase |
|
|
In this stage the DNA makes an exact copy of its self. |
Interphase |
|
|
In plant cells a cell plate forms. |
Cytokineses |
|
|
This stage is the first stage of the cell cycle. |
Interphase |
|
|
In this stage the nucleus turns into two nuclei. |
Mitosis |
|
|
In this stage the cell grows to its full size. |
Interphase |
|
|
In this stage the cytoplasm divides and organelles are divide. The parent cell becomes two daughter cells. |
Cytokineses |
|
|
This stage contains four phases. |
Mitosis |
|
|
This stage is the final stage of the cell cycle. |
Cytokineses |
|
|
A DNA strand looks like a.... |
Twisted rope |
|
|
A rung of a DNA strand is made up of.... |
A pair of nitrogen bases |
|
|
-In this phase the chromatin condenses to form rod like structures called chromosomes. |
Prophase |
|
|
-In this phase the chromosomes stretch out and the nuclear envelope forms around the nuclear region. |
Telophase |
|
|
-In this phase the nuclear envelope breaks down. |
Prophase |
|
|
-In this phase the chromosomes line up in the center of the cell and attach to spindle fibers. |
Metaphase |
|
|
-In this phase the centromere splits and the chromatids move to opposite ends of the cell. |
Anaphase |
|
|
Is the process by which a cell makes an exact copy of its DNA. |
DNA Replication |
|
|
What are chromatids? |
Identical strands of chromosomes x |
|
|
What forms around the chromatids during mitosis? |
Two new nuclei |
|
|
What is copied during replication? |
The cell's DNA |
|
|
During what stage of the cell cycle does replication occur? |
Interphase |
|
|
A DNA molecule is shaped like a |
spiral staircase |
|
|
A rung of a DNA strand is made up of.... |
A pair of nitrogen bases |
|
|
During DNA replication, adenine (A) always pairs with |
Thymine |
