IB 150 EXAM 2 QUESTIONS WITH COMPLETE
SOLUTIONS
2 Correct Answers diploid organisms have ____ types of
homologous chromosomes per type of chromosome
after meiosis 1 the ploidy of the cell becomes haploid bc each
cell only having one homologous chromosome per type of
chromosome
3' to 5' Correct Answers Direction in which the template DNA
is read during DNA replication.
5' to 3' Correct Answers direction of DNA strand synthesis
allele Correct Answers a version of a gene
allele Correct Answers product of a mutation event is called
an .........?
anaphase 1 Correct Answers homologous chromosomes
separate and are pulled to opposite ends of the cell
anaphase 2 Correct Answers Individual chromatids move to
each end of the cell
anaphase Correct Answers the stage of meiotic or mitotic cell
division in which the chromosomes move away from one
another to opposite poles of the spindle.
,the third phase of mitosis, during which the chromosome pairs
separate and move toward opposite poles
chromatids separate!
AND rule Correct Answers probability of one outcome
MULTIPLIED by the probability of another outcome
animals Correct Answers sperm + egg creates zygote
offspring produce gametes by MEIOSIS
asexual reproduction Correct Answers results in no genetic
diversity
mitosis
autosomal dominant Correct Answers Given trait is dominant,
the offspring can show trait or not. Individuals w/ trait in every
generation. Individual with it must have at least one parent with
it. Individual with the trait can have a child without it
autosomal recessive Correct Answers Two individuals show a
trait all the offspring will show the trait. Can skip generations. 2
individuals without the trait can have a child with it.
autosomal vs X linked Correct Answers Autosomal means # of
males and females affected will be roughly the same. X Linked
will always have more males w/ trait than females.
, autosomes Correct Answers Chromosomes that are not directly
involved in determining the sex of an individual.
bacterial sex Correct Answers asexual reproduction
results in offspring that are genetically identical because
bacterial sex is one round of mitosis
sharing plasmids and DNA
DOESNT allow for genetic diversity
base pairing rules Correct Answers the rules stating that in
DNA cytosine pairs with guanine and adenine pairs with
thymine and that in RNA cytosine pairs with guanine and
adenine pairs with uracil
base pairings Correct Answers A-T
G-C
carrier Correct Answers person who can pass on a recessive
allele for a genetically determined trait
may or may not show the trait phenotypically but might carry
one of the alleles
cell cycle Correct Answers The regular sequence of growth and
division that cells undergo
central dogma of biology Correct Answers DNA -> RNA ->
Protein
