Step by step
Solved in 2 steps
- Part a) and b) have already resolved and part c and d tobe resolved. a. What is a genetic mutation? How do genetic mutations differ fromsomatic mutations? b. What are mutagens? Using examples, describe how chemical andphysical mutagens cause mutations. c. Briefly describe the significance of transposons in inducing d. Discuss the practical aspects of mutations.Some mutations affect changes in protein structure and function that can result in disease whereas other mutations have no significant effects on protein structure and function. Please explain reasons for the above mentioned statement. Human civilization has resulted in a large number of potentially mutagenic chemicals (e.g. pesticides) and has changed the environment to increase the likelihood of encountering other mutagens, especially UV radiation. What roles should the authorities play in identifying mutagens and regulating their release into the environment?Name the two types of mutagens, give an example for each, and briefly describe how they cause mutations.
- Distinguish between spontaneous and induced mutations. Give some examples of mutagens that cause induced mutations.Earlier, we described the Lederbergs’experiment, which demonstrated thatmutations are not directed by the environment. But mutagens, which areenvironmental, can lead to mutations. What’s the difference?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.

What roles should the authorities play in identifying mutagens and regulating their release into the environment? Please discuss the subject in detail.Which 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.Although 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?
