Describe the structural organization of the prokaryotic genome and the eukaryotic genome.

A prokaryotic genome is often a single long DNA molecule. Eukaryotic genomes consist of a number of DNA molecules

List the phases of the cell cycle, describe the sequence of events during each phase.

Interphase is where 90% of the cell cycle occurs, the cell grows and copies its chromosomes in preparation for cell division G1 Phase, S Phase, G2 Phase. Mitotic phase: Mitosis and cytokinesis are broken down into 5 stages.

List the phases of Mitosis and describe the events that characterize each phase.

Prophase- chromosomes condense, sister chromatids joined at centromeres become visible. Prometaphase- Microtubules begin to attach to kinetochore and jerk chromatids back and forth. Chromosomes become more condensed

List the phases of Mitosis and describe the events that characterize each phase.

Metaphase is the longest stage of mitosis, Microtubules of spindle attach to kinetochores of sister chromatids. Anaphase-Microtubules go to opposite ends of the cell. Telophase-chromosomes decondense becoming less distict.

Describe the mitotic spindle.

Forms in cytoplasm during prophase. Assembly of microtubules starts at the centrosome. Nonkinetochore microtubules are responsible for elongating the whole cell during anaphase.

Describe the mitotic spindle.

Kinetochores-walk chromosomes along the microtubules which depolymerize at their kinetochore ends after motor proteins have passed.

Compare and contrast cytokinesis in animals and plants

In animals, cytokinesis occurs by a process known as cleavage. In Plants, vesicles from the Golgi Apparatus move along microtubules to the middle of the cell producing a cell plate, the cell plate enlarges until its surrounding membrane fuses withthe PM

Explain how the abnormal cell division of cancerous cells escapes normal cell cycle controls.

They may convey a growth factor's signal without the presence of the growth factors. They grow and divide on their own and do so at Random points.
