Quiz 1.2 The Cell Cycle and Mitosis

This diagram illustrates the process of mitosis.

Which of the following statements describes a chromosome as it goes through mitosis, from beginning to end?
1. Sister chromatids thicken and shorten, then line up along the middle of the cell, and split apart at their centromeres, and one chromatid goes into each of the two new cells
2. Two identical chromosomes fuse together at the middle of the cell, and one chromosome goes into each of the two new cells
3. The organelles of a cell replicate, the cell slowly splits in two, and chromosomes move from one cell into one of the new cells through the endoplasmic reticulum
4. Two chromosomes join together at a centromere to form sister chromatids, they line up along the middle of the cell, and one chromosome goes into each new cell
Which of the following statements about the cell cycle is least accurate?
1. Mitosis results in organisms producing reproductive cells
2. Repairs to the organism can occur as new cells are produced
3. Cells that are likely to be damaged or injured can be replaced frequently
4. Young organisms grow larger and develop specialized structures
Which of the following would not affect the rate of mitosis in your body?
1. Sitting in a seat on the bus that always has sunlight shining through the same window in the morning
2. Moving to Calgary, which is at a much higher altitude
3. Taking bacteriostatic drugs to fight an infection
4. Taking cytostatic drugs to fight a cancer
What term is used to describe the death and removal of a cell that is no longer useful to an organism?
1. Apoptosis
2. Regeneration
3. Cytokinesis
4. Epidermis
A cell mutates when exposed to cigarette smoke. It does not stop dividing, does not stick to normal cells around it, and can move from one location of the body to another. What kind of cell is this?
1. Cancer cell
2. Apoptotic cell
3. Replicating cell
4. Normal cell
Which of the following statements best describes human chromosomes?
1. Humans have 46 chromosomes, which can be arranged into 23 pairs
2. Humans have 12 chromosomes, which can be arranged into 6 pairs
3. Humans have 64 chromosomes, which can be arranged into 32 pairs
4. Humans have 254 chromosomes, which can be arranged into 127 pairs
