Textbook Question
Chapter 11, Problem 10TYK
A mutation in a single gene may cause a major change in the body of a fruit fly, such as an extra pair of legs or wings. Yet it probably takes the combined action of hundreds or thousands of genes to produce a wing or leg. How can a change in just one gene cause such a big change in the body?

One unexpected result of the sequencing of the human genome was the finding that mutations in a single gene can be responsible for multiple distinct disorders. How do you think mutations in a single gene can have such diverse effects?
If you have a mutation in your skin cells from falling asleep in a tanning bed, how will this affect your offspring?
Group of answer choices
It won't affect them because mutations cannot be passed down to offspring
It will affect their entire body because their entire body grew out of the fertilized egg
It will affect your offspring's skin cells only
It may affect them, depending on whether those particular skin cells are passed on to them
It won't affect them because the mutation is not in a gamete
Is it possible for their to be a mutation where an individual has incomplete or missing sets of chromosomes? or Would that simply result in the loss of life? I would say an easier way to describe a genome is by calling it either a blueprint of DNA or referring it as one full set of genetic information.

- When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in human cells than there are different genes in the genome. How can this be explained?arrow_forwardWhich of the following statements best describes the outcome of a mutation? a. A mutation always results in a mutant genotype b. A mutation always results in a mutant karyotype c. A mutation always results in a mutant phenotype d. A mutation always results in a mutant proteinarrow_forwardWhich among the following statements is not true about mutations? * a.) It may either occur at the chromosomes or at the sequence of nucleic acids. b.) It is caused either by mutagens or through hereditary genes. c.) All mutations cause diseases and disorders in the developing organism. d.) All mutations causes a change in the structure or sequence of the genetic material.arrow_forward
- After watching the video “Genes as Medicine" discuss how gene therapy has been used to treat an inherited form of blindness, and now sickle cell anemia. How were the genes delivered? What model organism was gene therapy tested in? How successful has the treatment been in humans?arrow_forwardOccasionally, a person is found who has one blue eye and one brown eye or who has a sector of one eye a different color from the rest. Can these phenotypes be explained by new mutations? If so, in what types of cells must the mutations occur?arrow_forwardGenes come in different versions called _________. What term describes the condition where the two copies are identical? What term describes the condition where the two copies are different?arrow_forward
- Which of the following statements best describes the effect of mutations in DNA? A Mutations result in changes that can be positive, be negative, or have no consequences B Mutations result in changes that always have negative consequences C Mutations result in changes that cannot be detected unless it is revealed by genetic screening D Mutations result in changes that have no consequencesarrow_forwardAlthough it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. Why is this done? What precautions need to be taken?arrow_forwardSuppose that a mutation resulted in a tapeworm that did not have hooks. Assuming this tapeworm was a human parasite, what is the most likely explanation of the effect might this have? The tapeworm would spread throughout the human body. The tapeworm would complete its entire life cycle inside the human host. The tapeworm would not remain in the digestive tract very long. The tapeworm would not be able to enter the human body. The tapeworm would reproduce more to compensate for a lack of hooks.arrow_forward
- A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors. All BUT ONE of the statements below correctly describes or explains genetic mutations. A) Mutation can disrupt normal cell activity and cause diseases, like cancer. B) Mutations in parents' cells are then passed down to offspring via reproduction. C) Our cells can recognise any potentially mutation-causing damage and repair it before it permanent. D) Mutations can occur as the result of exposure to environmental factors such as smoking, toxins and radiation.arrow_forwardSickle cell anemia is a disease caused by a mutation at the genotypic level. A person with two copies of the gene has the disease, but a person with one copy of the gene does not have the disease. The diagram shows how this mutation affects an organism. Use the image to answer the question. The mutation causes the deformity of the red blood cell, the component of blood that carries oxygen throughout the body. The deformed cells can clump together and can clog blood vessels. The parasites responsible for the sickle cell condition are killed in the deformed red blood cells. In which type of environment would carriers of the disease be naturally selected for? A. low altitude B. high altitude C. low population of parasites D. high population of parasitesarrow_forwardRegarding Adaptation and mutation do natural disasters or environmental change always cause negative impacts? Why or why not? And do mutations always cause negative impacts? Why or why not?arrow_forward
