1.1.4 Quiz: Mitosis
Question 8 of 10
2 Points
Genetic disorders can result when sister chromatids fail to separate properly.
During which phase is this problem most likely to occur?

Anaphase

Explanation:

It's in the anaphase that the spindle fibres holding onto the kinetochores of the sister chromatids will shorten and divide the centromere. Then, the sister chromarids will be pulled towards the opposite cell poles.

what subject is this

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
