What is the Chromosome Structure?
|
DNA that coils up around histone proteins.
|
|
What are the two types of chromosomes?
|
Sex Chromosomes which determine the sex of the organism and Autosomes which are all the other chromosomes.
|
|
What are Homologous Chromosomes?
|
The two copies of the same chromosomes.
|
|
What is the difference between diploid cells and haploid cells?
|
Diploid has the full amount of chromosomes in a human=46.Haploid has the half amount of chromosomes=23.
|
|
What is the 2 types of Cell Division?
|
1. Mitosis:2 new cells that are identicle to the parent cell.
2: Meosis:Cells divide to form haploid cells. |
|
What are the divison of cell nucleus?
|
Prophase, Metaphase, Anaphase,and Telophase.
|
|
What happens during Prophase?
|
Chromosomes are doubled.
|
|
What happens during Metaphase?
|
Nucleus dissapears. Chromosomes line up.
|
|
What happens during Anaphase?
|
Chromosomes split and move to opposite sides of the cell.
|
|
What happens during Telophase?
|
Nucleus reforms around chromosomes.
|
|
What happens durring Cytokinesis in animals?
|
Cytokinesis begins with a pinching inward of the cell membrane in the middle between the dividing cell into two cells.
|
|
What happens during Cytokinesis in plants?
|
The area of the cell membrane that pinches in and separates the cell in two.Vesides formed by Golgi apparatus fuse at the midline of cell,that forms a membrane bound cell wall. The nthe cell separates.
