If chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle, then fusion of a cell in G1 with a cell in early M phase would most likely result in the
(A) replication of chromosomes only in the G1 cell
(B) exiting of both cells from the cell cycle and into the G0 phase
(C) condensation of chromatin in preparation of nuclear division in both cells
(D) transfer of organelles from the G1 cell to the cell in the M phase
Please select the correct option. For the incorrect options, please explain why each one is incorrect. Thank you.
Name the stage of cell cycle at which one of the following events occur:(i) Chromosomes are moved to spindle equator.(ii) Centromere splits and chromatids separate.(iii) Pairing between homologous chromosomes takes place.(iv) Crossing over between homologous chromosomes takes place.
Explain why we can say that M-phase of the cell-cycle is triggered by a positive feedback loop.
a) What would the consequences be if cohesins were working normally but condensins were not? and b) what stage of the cell cycle would this cause problems in?
Why is it important for the centrosome to duplicate during G1-G2 (interphase) before M phase?
The kinetochores serve as a link between the sister chromatids and the microtubules attached to the mitotic spindle. a) How are microtubules still able to exhibit dynamic instability after they are bound to the sister chromatids and b) why is this important to mitosis?
As the name suggests, the Anaphase-promoting-complex (APC), promotes the 4th phase of mitosis by separating the sister chromatids so they can travel to separate poles of the cell, and prevents them from being re-zipped together. Describe how APC does these two things (Hint: one involves M-cyclin and the other involves…
