Document Summary

Cell division is the process in which the genetic information of a cell is faithfully passed along to the next generation of cells. _equal distribution of dna to opposite ends of the dividing cell. ___asexual reproduction__ is the type of reproduction involving only _one parent___. Binary fission is the type of _cell division which prokaryotes use to reproduce __. (fig. In bacteria since there is only a _single chromosome_____ the __cell cycle is less complex_____ (fig. __membranes elongates _ between the two copies until the cell is twice its normal size. _a cell wall forms between the two daughter cells _____. In bacteria since there is only a single chromosome, the cell cycle is less complex. If the organism is _single celled__, then a cell cycle can be the same as the life cycle. In eukaryotes, each round of growth and division makeup a cell cycle.

Part A:

In prokaryotes and eukaryotes cell reproduction is similar in that it requires some kind of signal to proceed, DNA replication, careful separation of the DNA into two equal portions, and division of the cytoplasm. How is cell reproduction different in prokaryotes and eukaryotes?

Select one:

a. In a eukaryotic organism, the signals for cell division are usually not related to the environment but to the function of the entire organism.

b. Eukaryotic cells constantly divide whenever environmental conditions are adequate and the cells are large enough.

c. The linear chromosomes in prokaryotes are constantly being updated.

d. Prokaryotic cell division requires cytokinesis before mitosis because of their small size.

e. The sexual phase of most prokaryotes (bacteria) is essential to the rapid cell division required for infection.

Part B:

What does the name Cyclin Dependent Kinase stand for?

Select one:

a. A protein important to the cell cycle that is dependent on DNA synthesis.

b. An enzyme that cuts DNA so that chromosomes can segregate.

c. An enzyme that phosphorylates other proteins using ATP only when the protein Cyclin is bound to the enzyme.

d. An enzyme that rolls along microtubules dragging a vesicle.

e. An enzyme that connects chromosomes to the spindle fiber.

Part C:

The Cell Cycle is divided into Mitosis, Cytokinesis, and Interphase. Mitosis can be ordered into the following phases:

Select one:

a. Prophase/Prometaphase/Metaphase/Anaphase/Telophase

b. Anaphase/Prometaphase/Metaphase/Prophase/Telophase

c. Metaphase/Anaphase/Telophase/Prophase/Prometaphase

d. Telophase/Prophase/Prometaphase/Metaphase/Anaphase

e. Anaphase/Telophase/Prophase/Prometaphase/Metaphase

Part D:

The Cell Cycle is divided into Mitosis, Cytokinesis, and Interphase. Interphase can be ordered into the following phases:

Select one:

a. S/G1/G2

b. G2/G1/S

c. G1/S/G2

d. G2/S/G1

e. G1/G2/S

Every year, the viral strains included in vaccinations for the flu are slightly different, based on the prevalence of the strains present the previous year. Which of the following statements is TRUE regarding the vaccinations and the treatment of viral infections like the flu?

	A.	When someone who is vaccinated encounters the virus they were vaccinated for, antigens are produced triggering destruction of the virus.
	B.	Antibodies are built up in response to viral antigens, making those with vaccines more susceptible to viral infection.
	C.	Viruses mutate quickly due to overuse of antibiotics.
	D.	Vaccinations involve introducing an antigen of a virus into the immune system, which stimulates the production of antibodies.

Recall that HIV is a retrovirus. Based on that, which of the following would NOT be an effective drug target for treatment of HIV?

	A.	Translation inhibitors
	B.	Integrase inhibitors
	C.	Reverse transcriptase inhibitors

The type of horizontal gene transfer that specifically requires a virus to transfer DNA from donor to recipient is called:

	A.	transformation.
	B.	conjugation.
	C.	transduction.
	D.	binary fission.

Binary fission differs from mitosis in that

	A.	binary fission occurs in prokaryotes, and mitosis happens in eukaryotes.
	B.	binary fission does not have a step to duplicate the genetic information, and mitosis does.
	C.	binary fission creates daughter cells that are genetically identical to the parent cell, while mitosis introduces genetic variation.
	D.	binary fission does not have a step to separate the parent cell into two daughter cells, and mitosis does.

Bacteria contain ______ in their cell walls, while Archaea contain _____ in their cell walls.

	A.	chitin; peptidoglycan
	B.	peptidoglycan; pseudopeptidoglycan
	C.	pseudopeptidoglycan; peptidoglycan
	D.	peptidoglycan; chitin
