Answer:
e. Centrioles send out microtubules, which bind to kinetochores to pull chromatids apart.
Explanation:
The centrioles are structures formed by microtubules that move to opposite poles during cell division, while the microtubules are polymers of tubulin that conform to the cytoskeleton, which provides the structure to the cell and is associated to its division during mitosis and meiosis. The kinetochore is assembled in the centromere region where binds the chromosomes to the mitotic spindle microtubules. These filaments (microtubules) bind to the kinetochore of sister chromatids in order to separate them during anaphase.
Answer:
The correct answer is: B, C, D,F, G, H.
Explanation:
Aneuploidy is a defect on the number of chromosomes a cell has. Human cells have 46 chromosomes, an additional chromosome (47) or a missing one (45) is an aneuploidy. Aneuploidy is usually due to a defect during cell division (chromosomes don’t separate). The following disease are examples of aneuploidy:
b. Down's syndrome (trisomy of chromosome 21)
c. Edward's syndrome (trisomy of chromosome 18)
d. Jacob's syndrome (a male with an extra Y chromosome)
f. Turner's syndrome (a female missing a X chromosome)
g. Klinefelter's syndrome (a male with an extra X chromosome)
h. Patau's syndrome (trisomy of chromosome 13)
