In what ways does cell reproduction in prokaryotes and eukaryotesdiffer? Could mitosis or meiosis occur in prokaryotes? Why or whynot?

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

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

Recap/Brush up: What is the difference between Mitosis andMeiosis? For simplicity, assume that the division of nuclei isfollowed by cell division (M-phase contain cytokinesis).

Note: if this is for a prep, then drawing a roster or gridmatrix may be helpful for answering and learning.

In Mitosis, the number of chromosomes(remains unchanged, isdivided in half, is duplicated); in Meiosis it is (remainsunchanged, is divided in half, is duplicated)

Cells resulting from Mitosis have (twice the, the same, halfthe) number of gene sets of the predecessor cell; cells resultingfrom Meiosis have (twice the, the same, half the) number of genesets of the predecessor cell.

Cells resulting from Mitosis (twice the, the same, half the)number of Loci of the predecessor cell; cells resulting fromMeiosis have (twice the, the same, half the) number ofLoci of thepredecessor cell.

If the the predecessor cell is diploid, then cells resultingfrom Mitosis (are haploid, are triploid, are diploid, cannotoccur); cells resulting from Meiosis (are haploid, are triploid,are diploid, cannot occur).

If the the predecessor cell is haploid, then cells resultingfrom Mitosis (are haploid, are triploid, are diploid, cannotoccur); cells resulting from Meiosis (are haploid, are triploid,are diploid, cannot occur).

If the the predecessor cell is triploid, then cells resultingfrom Mitosis (are haploid, are triploid, are diploid, cannotoccur); cells resulting from Meiosis (are haploid, are triploid,are diploid, cannot occur).

Mitosis consists of (one, several, two, three)cycles of phases,resulting in(two,one,several,four) cells; Meiosis consists of (one,several, two, three) cycles of phases resulting in(two,one,several,four) cells.

Different from Mitosis, Meiosis(isolates,recombines, justduplicates) each allele. In fertilization, allelesare(recombined,isolated).
