Bio 111 Chapter 10 Pre-HW – Flashcards

Which of the following represents the correct order of the phases of the cell cycle?

Which statement about mitosis and cytokinesis is TRUE?

During the G2 phase, the cell is preparing for mitosis. Using your knowledge of cellular organelles and molecules, Which molecule is produced in the highest quantity during the G2 phase?

Which of the following events do NOT occur in prophase of mitosis?

Why do chromosomes condense during prophase?

Docetaxel is a drug that is used in the treatment of cancer. It interferes with cell division by inhibiting microtubule depolymerization. Specifically, what effect will this have on mitosis?

A pregnant mother recently had an ultrasound that indicated massive defects in the formation of her unborn baby's heart. Other oddities were noted in the spinal cord region, the kidneys, and the formation of the facial features. She had an amniocentesis to examine the baby's karyology, and it was noted that there was a deletion of a small piece of one chromosome. The doctors advised her that her that she would likely miscarry. The devastated parents consult you as a genetic advisor on the likelihood that a future pregnancy would end similarly. What advise do you give this unfortunate couple?

Which of the following statements about the mitotic spindle is TRUE?

If the cohesin proteins failed to degrade during the metaphase/anaphase transition?

When does cohesin first associate with the sister chromatids?

The structure that divides the bacterial cell in two is termed the

In streptococci, why is new cell wall only produced in certain regions of the daughter cells?

The proteins ________ work together to free the transcription factor that is bound by the retinoblastoma protein.

Mutated forms of the Rb protein...

The protein ________ checks for damaged DNA, thereby acting as a "quality control" for the cell.

What mutation would allow the cell to divide when it should not and could possibly lead to cancer?

Which mutation would allow the cell to pass the G1 checkpoint when it should not?

The success of DNA replication is assessed during the ______ phase.

The cell cycle is regulated by checkpoints during the _______ phases.

A eukaryotic cell that receives a "go-ahead" signal at the G1 checkpoint of the cell cycle will

A cell that is in an environment that has an abnormally low pH will NOT pass which checkpoint?

DNA repair enzymes will be highly active during what phase of the cell cycle?

Growth factor receptors are typically found in the

If the protein retinoblastoma is ________, it can bind to and ________ the Myc protein.

The growth factors illustrated in this system are positive regulatory growth factors. Why are they considered 'positive' growth factors.

How does myc become active?

Mutations in the protein retinoblastoma (Rb) are often associated with cancer in the eye. What mutation might lead to cancer?
