1.In the chart:

A

B

C

D

+/+

100% functional protein

watery

no disease

+/-

50% functional protein

intermediate

no disease

-/-

0% functional protein

thick

disease

What is in column A?

  1. Different genes
  2. Different phenotypes
  3. Different genotypes
  4. Different loci
  5. Different proteins

2. 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)

  1. a +/- genotype will have a mild form of diabetes
  2. a -/- genotype will have diabetes
  3. a -/- genotype may not have diabetes
  4. a +/- genotype will have a 50% probability of diabetes
  1. a +/+ genotype will not have diabetees

3. Remember that beta-cells produce insulin. Most beta cell growth (mitosis and cell division) occurs before age 2 or 3 but there is some growth until about age 40. At age 20, a point mutation in the gene that encodes insulin occurred during mitosis of a beta-cell in Jane. The mutation results in a non-functional insulin molecule. Because of this mutation, which statement is most likley?

  1. Jane is at a higher risk for pancreatic cancer
  2. Jane will have no adverse physological/health consequence
  3. Jane will acquire type II diabetes
  4. Jane’s children are at much higher risk
  5. Jane will acquire type I diabetes

4. 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

5. let's say HK1 (encoding the enzyme that transfers phosphate from ATP to glucose) has two alleles: + (which encodes a functional product) and - (which encodes a non-functional product). What is the functional product?

a. a transcript

b. a gene

c. a glucose

d. a transporter

e. a protein

Homework Answers

Answer #1

Ans-1)c)Different genotypes

Explaination:the pair of allele of a gene represent the genotype of that cell.

Ans-2) +/- genotype will have a 50% probability of diabete

Ans-3)Jane will acquire type IIdiabetes

Point Mutation results in non functional insulin which is enable to glucose conversion into glycogen And type2 diabetes arises in which insulin is produced but non functional.

Ans-4)Cystic Fibrosis is autosomal recessive because a person must have two copies of the "-" allele to express the phenotype.

Explaination:

Recessive diseasese which express when present recessive allele present in 2 copies .

Ans5)

protein

Explaination: DNA undergo transcription to produce mRNA which undergo translation to produce functional product ie protein

6. Red-green color blindness occurs in about 8% of males and .4% of females. Many genes contribute to Red-green colorblindness and most of these are sex-linked, which is the reason for the disparity in the frequency between males and females. Call the allele that encodes a functional product "+" and the allele that encodes a non-functional product "=". Why is Red-green color blindness more fequent in males? a.   because males inherit only a single X chromosome, which means that inheriting...

Protein misfolding can be an aspect of several different human disorders, including cystic fibrosis, Alzheimer's disease, and atherosclerosis. Many times, the misfolded protein is a membrane protein. In fact, a type of diabetes insipidus results from a mutation in the G-protein-coupled vasopressin 2 receptor that prevents the protein from making it to the cell membrane! Describe how this type of receptor would normally get targeted to the membrane (from the beginning of translation) and then propose one mechanism by which...

A neurological disease, spinocerebellar ataxia Type 1, is caused by a dominant allele of an autosomal polyQ-type triplet repeat gene called SCA1. Normal SCA1 alleles contain between 6-35 CAG repeats; pre-mutation alleles contain between 36-48 CAG repeats; and disease alleles contain between 49-88 CAG repeats. To determine whether or not you have a SCA1 pre-mutation allele, you prepare genomic DNA from some of your cheek cells and amplify the smallest possible region of your genome that contains the SCA1 gene...
