What effects do mutations have on organisms? O All mutations are harmful because they disrupt protein function or gene regulation % All mutations are beneficial to organisms because they improve protein function or gene regulation All mutations have no effect on organisms, because they do not significantly affect protein function or gene regulation Some mutations are harmful, some are beneficial, and some have no effect on the organism

Which of the following statements about mutations are true?* Mutations are always passed down to future generations. Mutations decrease the genetic diversity of organisms. Mutations occur only in somatic cells since they are diploid. Mutations are changes in the phosphate backbone of DNA which always have harmful effects. Mutations always cause a frameshift. Mutations can be harmful, neutral, or beneficial to the organism. Mutations are changes in the nucleotide sequence of a DNA molecule. Mutations may cause a change in the protein sequence resulting from the genetic code for that gene. O This is a required question Page 2 of 10 Next Back
Scientists look at thousands of mutagenized flies, one at a time, under a microscope. They are looking for flies that don't look like they have developed normally. They find a remarkable fly with an extra thorax and a complete extra set of wings. This is an example of: A crazy waste of time A forward genetic screen A reverse genetic screen

Transgenic mice and other model animals are used to study human neurodegenerative disorders to O produce tissues for transplantation O develop animals with desirable traits. produce genes for gene therapy. research molecular mechanisms of a human disorder. all of the choices are possible.
How might a better understanding of our genes be used in the field of medicine?
Scientists take the gene from the human cell and insert it into a bacterial chromosome. Bacteria turn this gene into protein, but this protein doesn't work. Also, scientists have detected in too many amino acids. What is the reason for this?
A researcher discovers a mutation in the promoter region of a gene that increases the rate of transcription and increases its ability to do its job. What type of mutation is this? Loss of function Gain of function Silent mutation Frameshift mutation
A single gene mutation causing several, seeming unrelated problems is called? O Entropy Pleiotropy Atrophy Dystrophy
Gene therapy is currently a fairly expensive treatment. For rare conditions, the fewer the people treated, the more expensive the treatment will be. But whatis the right price for a cure?
Why is it easier to identify spontaneous mutations in bacteria than in most eukaryotes? The mutations occur at a much higher frequency. Because bacteria have smaller genomes. The mutations can be induced via exposure to the bacteriophage. The mutations are expressed directly in descendant cells because bacteria are haploid. The mutations are visible as color changes within a bacterial colony.
