Each side of the duplicated chromosome is called a?
|
Sister chromatid
|
|
The pinching in of the cell membrane after cell division is called?
|
Mitosis
|
|
The point on the chromosome to which the spindle fiber attaches is called the?
|
Centromere
|
|
What begins to "disappear" during prophase?
|
Nucleus
|
|
What is another name for all the body cells?
|
Somatic
|
|
During what phase does the chromatin begin to coil?
|
Prophase
|
|
What is the process where one cell becomes two called?
|
Cytokinesis
|
|
A period of growth and development for the cell is called?
|
Interphase
|
|
Which fibers help to move the chromosomes around during mitosis?
|
Spindle
|
|
Part of the cell cycle when the DNA is copied is called?
|
Synthesis
|
|
Once the chromatids separate in anaphase what do they become?
|
Daughter Chromosomes
|
|
What phase is it called when the chromosomes are separated?
|
Anaphase
|
|
Each side of the duplicated chromosome is called a?
|
Chromatid
|
|
What cell part helps to build the spindle fibers?
|
Centriole
|
|
During what phase of mitosis does the new nuclei begin to reform?
|
Telophase
|
|
During what phase does the chromosomes line up in the middle of the cell?
|
Metaphase
|
|
*Interphase*
|
Cells growing, DNA coping, spindle fibers growing
|
|
*Phrophase*
|
Chromosomes have formed, spindle fibers are lengthing, nuclear membrane starting to dissolve.
|
|
*Metaphase*
|
Spindle fibers are apart of the cytoskeleton. Nucleus is competely gone.
|
|
*Anaphase*
|
Sister chromotids separate, spindle fibers go back into the centeriols, spindle fibers are shorter.
|
|
*Telophase*
|
Two new nuclei are forming, cell membrane is pinching inward.
|
|
*Cytokinesis*
|
The final pinching of the cell membrane to divide cytoplasm. Cell plate forms to fully divide the two cells.
|
|
Result of Mitosis
|
2 new genetically identical diploid daughter cells
|
|
Cell is growing and producing more organelles.
|
Growth 1
|
|
During _____ of the cell cycle the genes are being copied.
|
Synthesis
|
|
Cell continues to grow, cell will stop here or move on to mitosis. Cells that don't go into mitosis can't divide.
|
Growth 2
|
|
Is a process when one cell becomes two. Nucleus divides to form 2 new IDENTICAL nuclei in a series of steps.
|
MITOSIS
|
|
Is the final division of the cytoplasm
|
CYTOKINESIS
|
|
Growth 1, Synthesis, and Growth 2 are all apart of?
|
INTERPHASE
|
|
**Importance of cell Division**
|
1. Growth
2.Repair 3. Development 4. Replacement |
|
**The Cell Cycle**
|
Interphase(longest phase)
1. A period of growth and development *Cells that no longer divide stay in interphase 2. Copying of hereditary material occurs *Each of the 2 new cells need a set of directions |
|
Picture of an organism's chromosomes is called a?
|
Karyotype
|
|
Nitrogen Base Rules:
|
A pairs with T
C pairs with G The only time nitrogen bases will be the same is if you are twins. |
|
A- stands for?
|
Adenine
|
|
T- stands for?
|
Thymine
|
|
C- stands for?
|
Cytosine
|
|
G- stands for?
|
Guanine
|
|
Chromosome # when the chromosomes are found in pairs. 2n = 46 for humans-somatic or boyd cells.
|
(2n) Diploid
|
|
Chromosomes # when the chromosomes are not found in pairs. n = 23 for humans Gametes/sex cells
|
(n) Haploid
|
