________ is when the spindle fibres shorten and pull the chromosomes apart to the two poles.
New cards
2
Metaphase
________ is when the spindle fibres attach to the chromosomes at the centrometre (a constricted region of a chromosome)
New cards
3
Mitosis
________ is the process of cell division, in which the cell divides into two, and then into two again and again.
New cards
4
Prophase
________ is when the DNA unwinds and condenses into chromosomes and the nucleus breaks down.
New cards
5
cell cycle
The ________ contains 6 main steps= Interphase (in between), prophase (prepare), metaphase (middle), amaphase (apart), telophase (two) and finally cytokinesis (division)
New cards
6
Rejection
________ can often happen in treatments to cure leukaemia as ________ can occur when trying to give the patient white blood cells, and the white blood cells could attack the cells of either the patient or the cells that were implanted.
New cards
7
cytokinesis
Finally, ________ is when the cytoplasm splits to create two separate genetically identical diploid cells.
New cards
8
Zygote
________- fertilised egg cell.
New cards
9
Telophase
________ is when a nuclear membrane forms around each set of chromosomes, separating them to form two new nuclei.
New cards
10
Clone
________- to make a genetically identical copy.
New cards
11
Embryos
________ are made from mitosis when the egg cell becomes a zygote (fertilised egg cell) and divides to make the ________.
New cards
12
Differentiation
________ happens at a young age, and so all specialised cells are made at the early stages of life.
New cards
13
Cell Division
Stage one (________)- Replication of DNA to form two copies of each chromosome and synthesis of new subcellular structures.
New cards
14
arent split
During Mitosis, the chromosomes ________- the chromosome amount stays exactly the same in the previous cell, and the cell which was made from the previous cell will have the exact same amount of chromosomes as the previous cell.
New cards
15
Adult stem cells
________ are found only in certain places in the body within differentiated tissues for example bone marrow.
New cards
16
Stem cells
________ can cure illnesses such as cancer, leukaemia, Huntingdons and Parkinsons disease.
New cards
17
cell division
The tissue at the tip of the plant where ________ takes place.
New cards
18
Differentiate
________- to change from undifferentiated to ________.
New cards
19
Stem cells
________ can divide and differentiate through mitosis.
New cards
20
