BIO 100 EXAM 2 ACTUAL TEST QUESTIONS
AND SOLVED ANSWERS
◉ do you have more than one allele?
Answer: Because humans are diploid, you usually have two alleles
for each gene:
One from your mother
One from your father
◉ mitosis
Answer: Division of the nucleus - karyokinesis
Asexual process
Simple cell division
Purpose - for growth and repair
◉ PMAT
Answer: prophase, metaphase, anaphase, telophase
◉ prophase
Answer: Centrosomes migrate to opposite ends of the cell
Nuclear membrane disintegrates
, Chromosomes condense
Spindle apparatus forms
Microtubules form a football shaped spindle between the 2 pairs of
centrioles
◉ metaphase
Answer: Line up at the equatorial (metaphasic) plate
◉ anaphase
Answer: Chromosomes break at centromeres, and sister chromatids
move to opposite ends of the cell
◉ telophase
Answer: Chromosomes reach the poles and begin to decondense
Spindle fibers break down
Nuclear membrane reforms
◉ cytokinesis
Answer: division of the cytoplasm
◉ what happens during cytokinesis?
