Kinetochores control the transition from metaphase to anaphase. Why is this statement true? Question 7 options: a) Anaphase will only begin after the M checkpoint where all the kinetochores and mitotic spindle have correctly attached. b) Anaphase will only begin after the M checkpoint where all the mitotic spindle have correctly formed. c) Kinetochores bind to microtubules in monotelic attachment to the sister chromatids. d) Kinetochores bind to microtubules in syntelic attachment to the sister chromatids. e) Kinetochores will halt at the M checkpoint to weaken the mitotic spindle formation, which is the event that initiates anaphase.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

Kinetochores are protein complexes that assemble on the centromere of each chromosome. They are responsible for attaching the chromosomes to the microtubules of the mitotic spindle. This attachment is essential for the proper segregation of chromosomes during cell division.
The M checkpoint is a cell cycle checkpoint that occurs at the end of metaphase. It ensures that all of the chromosomes are properly aligned on the metaphase plate and attached to the microtubules of the mitotic spindle before anaphase can begin.
