What are the 3 major parts of the cell cycle?
Interphase Mitosis Cytokinesis Click Anywhere to Continue
What are the 3 parts of Interphase?
G 1, S, G 2 Click Anywhere to Continue
What is happening during Interphase?
The cell is growing and copying its DNA Click Anywhere to Continue
What is the last step of the cell cycle? What happens?
Cytokinesis – the cell splits into 2 daughter cells Click Anywhere to Continue
Why is the Cell Cycle important?
We need it to make new cells to grow, replace old cells, and fix injuries. Click Anywhere to Continue
What are the 4 parts of Mitosis?
Prophase Metaphase Anaphase Telophase Click Anywhere to Continue
What happens in Anaphase?
The chromosomes are pulled apart to either end of the cell. Click Anywhere to Continue
What happens in Prophase?
The chromatin (spaghetti mess) winds into chromosomes (x’s) Click Anywhere to Continue
In which step do the chromosomes line up in the middle of the cell?
Metaphase Click Anywhere to Continue
Which type of cells go through Mitosis?
Body cells Click Anywhere to Continue
What is the difference between Mitosis and Meiosis?
Mitosis – creates 2 new cells each with 46 chromosomes (makes body cells) Meiosis – creates 4 new cells each with 23 chromosomes (makes sex cells) Click Anywhere to Continue
Is different about the steps of Meiosis?
PMAT occurs twice Click Anywhere to Continue
What do we use Meiosis for?
To make sex cells Click Anywhere to Continue
What are the steps of Meiosis?
Interphase Prophase I Metaphase I Anaphase I Telophase I Cytokinesis Prophase II Metaphase II Anaphase II Telophase II Cytokinesis Click Anywhere to Continue
How many chromosomes do the cells of Meiosis have? WHy/?
23 – egg and sperm form the 46 Click Anywhere to Continue
What is the difference between Haploid and Diploid?
Haploid – 23 (n) Diploid – 46 (2 n) Click Anywhere to Continue
What is Chromatin?
A combination of DNA and protein Click Anywhere to Continue
What are Sister Chromatids?
Two identical, joined copies of chromosomes Click Anywhere to Continue
What is a Centromere?
The area where two chromatids are joined together Click Anywhere to Continue
What is another word for sex cells?
Gametes Click Anywhere to Continue
What is the longest part of the Cell Cycle?
Interphase Click Anywhere to Continue
At what stage does a cell split into two new cells?
Cytokinesis Click Anywhere to Continue
What stage starts to split the cell in half?
Telophase Click Anywhere to Continue
If we wanted to make more liver cells, which process would we use?
Mitosis Click Anywhere to Continue
What is Crossing Over?
The exchange of genetic material between two chromosomes Click Anywhere to Continue
