Biology 1001 LSUE Barton chapter 8 QUESTIONS WITH
ANSWERS RATED A+
What are the 2 phases of cell cycle? - interphase and mitotic phase
growing and dividing phase
What are the 3 phases of interphase? - G1, S, G2
initial growth
DNA replication
still growing
What the 2 phases of mitotic? - mitosis and cytokinesis
what is included in mitosis? - consists of: division of cells and P-MAT: prophase, metaphase,
anaphase, telophase
What is a centrosome? - organizes microtubules in preparation for mitosis
What is prophase in mitosis? - thickening or Colin got sister chromatids
What is metaphase in mitosis? - sister chormotids are moved to the middle of the cell by spindles
What is anaphase in mitosis? - sister chromatids separate to opposite poles
What is Telophase? - cell elongates forming a cleavage furrow in animal cell, while forming a
cell plate in plant cell. Nuclear membrane reappear; spindles disappear; chromosome thinning or
uncoiling
What is cytokinesis? - The cell divides in half to create two new cells
What are the 2 physical factors that effect the rate of cell division? - Anchorage-dependence
Density-depended inhibition
What is anchorage dependence? - the need for cells to be in contact with a solid surface to divide
What is density dependent? - cultured cells continue dividing until they touch one another
What has to happen for a cell to grow or divide? - the cell has to be stimulated
What signals the cell cycle control system? - growth factors
What controls the cell cycle? - Proteins called cyclins
