Bio 152 Exam 2 UPDATED Exam Questions
and CORRECT Answers
What are the results of mitosis? - CORRECT ANSWER - one cell produces two identical
daughter cells. Diploid cells (2n)
What are the results of Meiosis? - CORRECT ANSWER - one cell produces 4 daughter
cells. Haploid cells (n)
What are some characteristics of mitosis? - CORRECT ANSWER - the purpose is cell
proliferation - this allows growth and repairs within the organism. chromosome number stays the
same and there is no genetic variation (unless a mutation occurs). ○ Example: Human somatic
cells
What are some characteristics of Meiosis? - CORRECT ANSWER - the purpose is sexual
reproduction. The chromosome number is halved and genetic variation increases. ○ Example:
Human germ line cells
What are some characteristics both Mitosis and Meiosis have? - CORRECT ANSWER -
start with one parent cell, produce new cells, follow the same basic steps
Define Homologous Chromosomes - CORRECT ANSWER - pairs of chromosomes that
have the same size, shape, and genes. One set of chromosomes is from the mother and the other
from the father
Define Centrosomes - CORRECT ANSWER - main function is to organize the
microtubules and provide a structure to the cell. It also pulls the chromatids apart during cell
division.
Define Meiosis 1 - CORRECT ANSWER - the number of cells is doubled but the number
of chromosomes is not. This results in 1/2 as many chromosomes per cell
