let's say CFTR (encoding the CFTR Cl- channel) has two alleles: + (which encodes a functional product) and - (which encodes a non-functional product). CFTR is a Cl- transporter expressed in many epithelial cells. LDLR is on chromosome 7. A person with the -/- genotype has Cystic Fibrosis but those with either +/- or +/+ genotypes do not. Which of the following is true?
|
a. Cystic Fibrosis is autosomal recessive because a person must have two copies of the "-" allele to express the phenotype |
||
|
b. Cystic Fibrosis is autosomal dominant because the "+" allele is the normal version |
||
|
c. Cystic Fibrosis is autosomal dominant because the "+" allele is the most common in the population |
||
|
d. Cystic Fibrosis is autosomal dominant, because a person must have two copies of the "-" allele to express the phenotype |
||
|
e. Cystic Fibrosis is autosomal recessive because it is the "-" allele that causes the disease |
3.
let's say SLC2A4 (encoding the insulin-dependent glucose transporter GLUT4) has two alleles: + (which encodes a functional product) and - (which encodes a non-functional product). If GLUT4 expression is necessary to not have diabetes, which of the following can we definitely conclude? (More than one answer may seem correct but only one answer logically follows the information)
|
a. a +/- genotype will have a mild form of diabetes |
||
|
b. a -/- genotype will have diabetes |
||
|
c. a -/- genotype may not have diabetes |
||
|
d. a +/- genotype will have a 50% probability of diabetes |

|
e. a +/+ genotype will not have diabetees |
4.
a pretty good definition of a gene is
|
a. one of the homologous chromosome inherited from either the egg (mother) or sperm (father) |

c. one of two or more alternative forms of nucleotide that arise by mutation and are found at the same place on a chromosome. |
||
|
d. the mRNA that is translated into a polypeptide |
||
|
e. the bluprint for the phenotype |
