Bio 110 Exam 3 Study Guide Questions With Complete
Solutions
31. Compare and contrast mitosis and meiosis Correct Answers
a. Comparison:
i. Both go through the same 5 phases to produce daughter cells
b. Differences:
i. Mitosis produces two diploid daughter cells that are
genetically identical whereas meiosis produces four haploid
daughter cell that are genetically different
ii. Meiosis goes through synapsis (homologous pairs of sister
chromatids associate with each other lying side by side forming
a bivalent, crossing over (physical exchange between
chromosome segments of the bivalent increasing the genetic
variation of sexually reproducing species), and the nucleus
divides twice
35. Give examples of trisomies in autosomal chromosomes and
trisomies and monosomies in sex chromosomes in human
Correct Answers ...
anaphase Correct Answers pairs of sister chromatids split apart
at centromeres each chromatids is linked to only one of the two
poles by one or more kinetochore microtubule; kinetochore
microtubules shorten and overlapping polar microtubules slide
over each other pulling chromosomes toward opposite poles
binds a single-stranded DNA and prevents it from re-forming a
double helix Correct Answers single- strand binding protein
CHAPTER 12 Correct Answers CHAPTER 12
, Compare prokaryotes and Eukaryotes in transcription. Correct
Answers Eukaryotes have the same basic features identical to
prokaryotes except each step has more proteins
covalently attaches adjacent Okazaki fragments in the lagging
strand Correct Answers DNA ligase
define diploid and haploid. Name the types of humans that are
diploid and haploid Correct Answers Dipoid - 2 sets of
chromosomes
human body cells have 23 pairs with 46 total
haploid - 1 set of chromosomes
human gametes (sex cells) have 23 total
define meiosis Correct Answers a. The process by which
haploid cells are produced from a diploid cell; begins after a cell
has progressed through the G1, S, G2 phases of the cell cycle
(interphase) just like mitosis; key differences between meiosis
and mitosis: synapsis, crossing over, nucleus divides twice
define mitosis Correct Answers first part of M phase; division
of chromosomes; sorting process that ensures that each daughter
cell will obtain the correct number and types of chromosomes;
spindle is responsible for organizing and sorting the
chromosomes
describe crossing over. why is is beneficial Correct Answers a.
One of the differences between meiosis and mitosis; physical
