Directions: Write the correct number of chromosomes in the daughter cells after mitosis (asexual reproduction) has taken place.

The failure of chromosomes to separate normally during cell division is called

The nuclear envelope is broken into smaller components. Kinetochore microtubules are assembled and are connected to kinetochores. Name: The chromosomes become aligned in a plane at the cellular equator. Name:

Specify the correct number of chromosomes and chromatids in each of the following human cell types. A spermatagonial precursor about to enter meiosis has 46 chromosomes and chromatids. An egg cell has chromosomes and chromatids. A cell entering meiosis II has chromosomes and chromatids.

Explain how interference with mitotic structures or disruption of mitotic processes affects cell reproduction and ultimately the organism.

* Summary of mitosis

Answer each question with a paragraph; 3-5 sentences each.   Explain the difference between a proto-oncogene and a tumor-suppressor gene. Explain the difference between prokaryotic and eukaryotic cell division. Explain the difference between positive regulation of the cell cycle and negative regulation of the cell cycle. Explain the difference between normal p53 and mutated p53. Find two differences and two similarities between binary fission and mitosis.

The cell cycle is typically thought of as having four stages. Describe the stages of the cell cycle and identify the mechanism(s) involved in progressing or not progressing through the stages with reference to proteins and signalling processes involved. Please keep brief - 10 sentences/dot points max.

Label each stage of the cell cycle and describe the events that occur
