During which phase of the cell cycle is DNA replicated? O G1 phase O G2 phase O S phase O M phase

The drug cytochalasin B blocks the function of actin. Which of the following aspects of the animal cell cycle would be most disrupted by cytochalasin B? Spindle attachment to kinetochores DNA synthesis Cleavage furrow formation and cytokinesis Cell elongation during anaphase Spindle formation

During the cell cycle there are three checkpoints. Match each description with the correct checkpoint.                                                                        Requires growth signals and checks there are no mutation in the DNA                                                                        Checks that DNA is properly replicated and that all the organelles and proteins needed for division are present                                                                         Ensures that all the chromosomes are lined up and accounted for A. G1/S B. S/G2 C. G2/M  D. Metaphase/Anaphase E. Anaphase/Telophase

What celluar events/processes are associated with G1,S,G2,and M phases of the cell cycle? With the phases of mitosis? Some example: A. DNA replication B. Beginning of mitosis C. Normal cell growth and function D. Breaksdown of nuclear membrane E.Separation of sister chromatids F.Alignment of chromosomes on the equator of the cell H.Triggering the compaction and condensation of chromosomes I. Attachment of microtubles to kinetochores

Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle. Match each label to the correct locationn in the model. (use photo to know where  they be put)   ITEM BANK: Move to Bottom Cell double checks duplicated material for errors. Cellular contents excluding chromosomes are duplicated. Chromosomes are duplicated. Genetic material divided and 2 daughter cells form.   not graded

Which of the following statements regarding cyclin B is FALSE? Group of answer choices It is a component of the mitosis or maturation promoting factor (MPF) Its production and activation is linked to extracellular stimuli It interacts and activates CDK1 protein kinase Its destruction by APC/C signals the end of mitosis All of the above are true
