Objectives and Study Guide
Describe the structure of a chromosome.
Define genome,haploid, diploid, euchromatin, heterochromatin and chromatid
Describe the composition of chromosomes and explain how chromosomal structure
changes in preparation for cell division.
List the phases of cell cycle and describe the events that occur during each phase.
Describe what major events occur during the G1, S and G2 periods of interphase.
Distinguish between mitosis and interphase.
List the phases of mitosis and describe the events characteristic of each phase.
Know what is cytokinensis and how it is different in animals and plants.
List several factors which stimulate or inhibit cell growth.
Describe what point in the cell cycle determines whether a cell will divide and explain
the role of volume-to-genome ratio. (Focus on check points)
Explain how abnormal cell division of cancerous cells differs from normal cell division.
Explain karyotyping and the use of karyotypes
