Document Summary

The ability for a pre-existing cell to give rise to another cell is due to the regulated process of cell division. This process of cell division can mean different things to different organisms. For some cells, such as prokaryotic cells, cell division is also reproduction since the division of one prokaryotic cell will give rise to a new organism (made up of one cell). All of the essential elements necessary to reproduce cells are found in the prokaryotic cell. These cells are capable of making exact copies of their genomes and then segregating one copy of each genome to each of two daughter cells. The process of cell division in prokaryotes requires that identical genetic material is distributed amongst daughter cells. In prokaryotes, the process of cell division is a form of asexual reproduction that is often referred to as binary fission.

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

7.The portion of DNA that controls when and where proteins are synthesized

Question 2: Fill in the blank with these terms: dependent variable, independent variable, y-axis, x-axis

Understanding graphs is an important skill in science, since being able to visually depict data is often useful for identifying patterns, and can sometimes be the only tool for easily evaluating whether or not the data supports your hypothesis. When viewing a graph, the______ is plotted on the______, and the______we are measuring is plotted on the_____. For example, in one of the photosynthesis experiments last week, temperature was the______, while the size of the bubble at the end of the experiment was the_____
