1) colorblindness is a sex-linked trait located in the X
chromosome. Which of the following couples would have all normal
son, but the daughters will all be carrier? A) a color blind male
and a norml female B) a color blind male and femal who is
colorblind carier C) a normail male and female who is colorblind
carrier D) a male who is colorblind carrier and a colorblind female
E) a normal male and a colorblind female

2) Colorblindness is a sex- linked trait located in the X
chromosome. Which of the following couples would have all normal
sons, but the daughter will all be a carrier? A) A color blind male
and a normal female B) a color blind male and a female who is
colorblind carrier C) a normal male and a female who is colorblind
carrier D) a male who is colorblind carrier and a colorblind female
E) a normal male and a colorblind female

3) You see a recombination frequency of 50% between those genes.
Which of the following possibilities can you exclude? A) That the
gene are located close together on the same chromosome B) that the
genes are on different chromosome C) that the gene are assorting
independently D) that the gene are located on the same chromosome,
but very far apart

4) Testosterone is a lipophilic (hydrophobic) hormone release
during puberty. This is responsible of the long time changes that
we see happen during this developmental stage: facial and pubic
growth, increased muscle mass, and even undesired affects such as
acne. How is this testosterone producing such lasting affects? A)
It ultimately activated proteins already present in the cell B)
they cannot cross the plasma membrane, thus their receptor are
located extracellularly C) it uses activate transport in order to
move from high concentration in the blood to the low concentration
inside the cell D) it activated intracellular receptor that act as
transcription factor changing gene expression

5) Which of the following is false when comparing transcription
between prokaryotes and eukaryotes? A) Prokaryotes mRNA has
undergone multiple modification before translation B) eukaryotes
gene have introns that need to be removed before translation C)
Prokaryotes mRNA can be translated while it is still being
transcribed D) eukaryotes mRNA needs a 5’ cap and a 3’ tail to
prevent its degradation
