Exam 3: Chromosome Transmission During Cell Division and Sexual Reproduction

Vincristine is a cancer chemotherapy drug. It binds to tubulin dimers, inhibiting assembly of microtubules. Where do you predict that vincristine stops the cell cycle?

The process where two gametes fuse with each other in the process of fertilization to begin the life of a new organism is called

In several mammals, including some rat and shrew species, the presence of two X chromosomes means the animal will be a female, whereas having just one X chromosome dictates maleness. This type of sex determination is most similar to

If the gametes of an organism are different morphologically, they are said to be ________.

The physical structure that is formed when two chromatids cross over is called a(n) ________.

What represents the correct order of events during prophase I?

Oogenesis is a gametogenic process involving ________ that produces ________.

In plants, the haploid generation is called the ________ and the diploid generation is called the ________.

You are studying a type of cell that you don't know much about. You want to determine what organism the cell comes from. You decide to watch cell division in this plant using the appropriate cell biology tools. After some experimentation, you determine that cytokinesis in this cell is sensitive to myosin inhibitors. You are likely studying

During this phase of the cell cycle the separated sister chromatids are considered independent chromosomes.

During this phase of the cell cycle the chromosomes line up in the center of the cell.
