Describe the role of the following structures or proteins in cell division:

synaptonemal complex

How are chromosomes named on the basis of their centromere placement?

Contrast telophase in plant and animal mitosis.

Describe the phases of the cell cycle and the events that characterize each phase.

The nuclear DNA content of a single sperm cell in Drosophila melanogaster is approximately 0.18 picogram. What would be the expected nuclear DNA content of a primary spermatocyte in Drosophila? What would be the expected nuclear DNA content of a somatic cell (non-sex cell) in the G1 phase? What would be the expected nuclear DNA content of a somatic cell at metaphase?

Contrast the chromatin fiber with the mitotic chromosome. How are the two structures related?
