Chapter 22, Problem 8TY
Summary Introduction
Introduction: Proteins involved in performing many functions that are found in eukaryotic cells are known as actin. Actin plays an important role in muscle contraction and G-actin and F-actin are two forms in which it exists. The comparison of gene sequences in two species in order to find the common gene sequence is a technique of computational biology and is known as sequence homology.

- In humans, the AMY1 gene produces the enzyme amylase in cells of the salivary glands. Amylase breaks down starch (a polysaccharide) into the sugar maltose (a disaccharide). People from cultures with diets high in starch produce more amylase than people from cultures with diets low in starch because of a mutation in the AMY1 gene. Explain in two to three sentences why the frequency of this AMY1 mutation would have increased in frequency in populations with a high starch diet.arrow_forwardA scientist is curious about the effects of diet on the gut length of spadefoot toad tadpoles. She collects tadpoles from pools and dissects them to determine the length of their gut and their diet. She finds that tadpoles with longer guts have a diet that is mostly algae. What is a possible/likely implication of this finding? Group of answer choices A. diet affects gene expression B. they should make a movie about this scientist C. algae changes DNA sequences of genes D. there is a higher mutation rate among algae eaters E. tadpole form is not affected by genesarrow_forwardVarious strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.arrow_forward
- In comparison to experimental results from the genetic manipulation of an invertebrate model, what pathologic outcome(s) would suggest that multiple homologs of a disease gene are present in humans? a. Missing the essential gene homolog that is lethal in fruit flies is also lethal in human infants. b. Different homologs of the essential gene are each expressed in different human organs, and mutations in these duplicated genes cause organ-specific diseases. c. Different homologs of the essential gene are each expressed in different stages of early child development, and mutations in each of these duplicated genes cause different diseases. d. In humans, defects in different homologs of the essential gene cause different loss-of-function diseases due to subfunctionalization. e. The essential gene is lethal in fruit flies, but there is no disease phenotype exhibited in people.arrow_forwardThe diagram below shows the result of a hybridization experiment between a eukaryotic mRNA and the template strand of its gene. Which of the following statements is TRUE? a. This gene contains four exons. b. The gene’s exons are visible as unpaired DNA loops protruding from the DNA/RNA hybrid. c. The 5’ end of the RNA strand is on the right side of the drawing. d. A hybrid between a prokaryotic mRNA and its gene would result in a similar image. e. the poly-A tail of the mRNA hybridizes with a poly-T stretch in the DNA.arrow_forwardWhat are the most highly-conserved regions of human DNA (when compared to similar DNA sequences in closely-related animals)? A. transposons B. non-transcribed spacers C. introns D. pseudogenes E. exonsarrow_forward
- You are working in a lab that studies stickleback fish. These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! Question: Briefly explain a study you could do to test if the difference between the mutant and wild type fish was due to a difference in the structural gene that makes the spines or due to a difference in gene expression.arrow_forwardA scientist studies the production of a key digestive enzyme in silk moths. The moths have one gene for this enzyme, and the scientist extracts mRNA transcribed from this gene as well as protein translated from it. The gene has three introns in its sequence. If the researcher compares mRNA from inside the nucleus to mRNA from the ribosomes, what will be found? A. less mRNA in the nucleus B. shorter mRNA in the ribosomes C. identical mRNAs in both places D. mRNA covalently attached to protein in the nucleusarrow_forwardWhich of the following order of events correctly depicts the Central Dogma as it would occur in an eukaryotic organism? a.

Neurobiology of speech and language has been studied in a family in which half of the members have severe impairment in both speech and language. The mutation responsible for the phenotype was identified in the FOXP2 gene. In addition, this gene is found on a chromosome segment tightly linked to autism, a disorder in which language is impaired. How would you directly test the hypothesis that this gene is necessary for vocal communication in other mammals? a. Use molecular genetic techniques to disrupt (inactivate) the mouse Foxp2 gene and observe the effect on ultrasonic vocalizations in the knockout mice. b. Determine the DNA sequence of the FOXP2 gene in several species of mammals that communicate vocally and compare these sequences to the DNA sequence for the human gene to determine whether the gene is evolutionarily conserved. c. Compare neural expression patterns of the FOXP2 gene between species that communicate vocally and related species that do not communicate vocally to…arrow_forwardOver several years, researchers learned more about proteins and the genes which code for them, the findings of which lead them to revise the original one gene-one enzyme hypothesis. Which of the following is NOT one of the findings which led to revision? a. many genes code can code for RNA molecules which never go on to produce a protein at all b. oftentimes, many genes are required to produce a single protein, where one gene produces one polypeptide and many polypeptides together make the single protein c. in addition to enzymes, gene products also include non-enzyme proteins like keratin and insulin d. a single gene produces one specific enzyme e. a single gene may code for multiple different (closely related) polypeptidesarrow_forward
