You have the following DNA coding sequence of a wild-type allele: 5’-ATG TTC CAG CTA GAT GAT ATG CTG GTA ATT GGG GAA CGC GCG CGG TAA-3’ For each of the following mutations: A. State whether the mutation is missense, nonsense, frameshift, or silent. B. Write the codon change that occurs for the missense, nonsense, and silent mutations (ex. GAA -- GAT). C. For frameshift mutations, write out the entire mutant sequence with each codon clearly indicated (if the frameshift creates a new stop codon, end the sequence at the new stop). Using the wild type DNA sequence above as a guide : Write the amino acid sequence of the mutants. Mutant 1: transition at nucleotide 23 Mutant 2: T --> G transversion at nucleotide 29 Mutant 3: an insertion of “A” after nucleotide 14 Mutant 4: transition at nucleotide 7 Mutant 5: An insertion of GG after nucleotide 40 Mutant 6: transition at nucleotide 15 Mutant 7: a deletion of nucleotide 25
1. A monogenic disease is a disease caused by a mutation in a single gene. For instance, sickle-cell anemia is caused by a mutation in the HBB gene, which codes for the B- globin chain of hemoglobin. The beginning of HBB is shown here: 5'-ATGGTGCACCTGACTCCTGAGGAGAAGTCTGCCGTTACT...-3' A. Translate this HBB sequence into an amino acid sequence. B. In terms of amino acids, what is the result of the sickle cell mutation, wherein the bolded red A is changed to a T? This single mutation causes hemoglobin to aggregate, causing red blood cells to deform into a sickle-like shape rather than the normal “biconcave disk" shape. C. What would happen if the bolded blue A were mutated to at T? (This is hypothetical; it's not a mutation found in sickle-cell disease.)

4. Different populations of mouse L-cells that lack cadherins were transfected with either E- cadherin or P-cadherin. If cells expressing E-cad are mixed with those expressing P-cad, they segregate into distinct balls of cells (A in figure). However, if cells expressing different levels of the same cadherin are mixed, they form a single ball, with the high expressing cells in the center B in the figure). (A) E-cadherin SORTING OUT P-cadherin (B) low P-cadherin SORTING OUT high P-cadherin Why do the cells expressing different levels of cadherin segregate as in (B) in the figure, and why not into two separate balls, or one ball with a different organization (randomly mixed, or high expressors on the outside)?
The photos above show flowers from Arabidopsis plants. One plant is wild-type (unmutated); the other carries a mutation in one of its ABC floral identity genes. This mutation causes sepals and petals to form instead of stamens and carpels. Refer to Figure 10.8 to decide which gene (A, B, or C) has been inactivated by the mutation.
b d f a + + + + d + e The normal flower color in garden peas is purple. A researcher interested in the biochemical pathway leading to purple flower color has isolated six white mutants, each of which is recessive to purple. The six white mutants have been designated a, b, c, d, e and f. Complementation tests have been carried out for each pair of mutants, and the results are indicated in the table above, where a “+" indicates complementation (purple flower color in the offspring of the complementation test) and a “-" indicates no complementation (white flower color). What is the number of genes (complementation groups) identified by these mutants? +| +|+|+|+
#2.) Mary wants to further confirm if she is a carrier for this lethal gene. She was told that a new SNP marker was identified RFPL marker. She requested to do SNP test for all the DNA samples. The results are: her parents are heterozygous for SNPs (that is to say, one chromosome is wild-type and another one contains the SNP). The sister who passed away is homozygous for the SNP. Mary does not have this SNP. So now what is the probability of Mary as a carrier of the death gene?

Cystic fibrosis (CF) is a genetic disorder affecting a number of organs, including the lung airways, pancreas, and sweat glands. Mutations in both copies of the CFTR gene causes cystic fibrosis. Imagine that you have sweat gland samples from several Cystic Fibrosis patients (A-C) with unknown mutations in CFTR. You also have normal (+) sweat gland sample to use as a positive control. А В С А В С Choose which mutation would explain the RNA and protein results in A, B, & C: 1. Promoter/Regulatory mutation 2. Silent mutation 3. Missense mutation 4. Deletion mutation 5. Splice site mutation 6. Nonsense mutation RNA gel Protein gel
5. Chapter 21 describes two blotting methods (i.e., Northern blottingand Western blotting) used to detect gene products. Northern blottingdetects RNA and Western blotting detects proteins. Supposethat a female fruit fly is heterozygous for a maternal effect gene,which we will call gene B. The female is Bb. The normal allele, B,encodes a functional mRNA that is 550 nucleotides long. A recessiveallele, b, encodes a shorter mRNA that is 375 nucleotideslong. (Allele b is due to a deletion within this gene.) How couldyou use one or more of these techniques to show that nurse cellstransfer gene products from gene B to developing oocytes? Youmay assume that you can dissect the ovaries of fruit flies and isolateoocytes separately from nurse cells. In your answer, describeyour expected results.
