- Gene mutations can be classified in two major ways:(1) hereditary or germline mutations that are inherited from a parent and are present throughout a person’s life in virtually every cell in the body.(2) acquired or somatic mutations that occur at some time during a person’s life and are present only in certain cells, not in every cell in the body.If there is no family history of a particular disease but a child has the disease then it may have arisen due to a(n) ________ mutation early during development. A) acquired B) inherited C) silent D) transitionMutagens, when introduced to the body can always cause cancer. Is this statement true? Select the correct response: No. Mutagens do not necessarily, directly equate to the cause of cancer. A cancer is usually caused by a substance called carcinogen that increases the probability of inducing a tumor. Mutagens can be limited to the result of spontaneous or induced mutations that causes changes and/or errors in the coding and reading of the DNA strand and in the genetic make- up of the organism involved. Though some mutagens are considered as carcinogens, not all mutagens can lead to cancer. Yes. The terms can be used interchangeably even in the medical field. Yes. Mutagens does equate to the cause of cancer. A cancer is usually caused by a substance called carcinogen that increases the probability of inducing a tumor. However, mutagens is not only limited to the result of spontaneous or induced mutations that causes changes and/or errors in the coding and reading of the DNA strand and in…Mutations that eliminate the function of a protein are generally associated with: missense changes in a small number of codons in a gene mutations creating UGA, UAA or UAG sequences in introns base pair changes that occur within the promoter of a gene activating mutations in proto-oncogenes that cause growth mutations in tumor suppressor genes that lead to cancer A scientist is doing a PCR experiment where she is using PCR primers where the 5' ends have a radioactive phosphorus atom (33P) on them.

- Mutations in DNA may or may not result in a change in the phenotype of an organism. In which of the following situations will a mutation appear in the phenotype of an individual? The mutation occurs in an organism which is past reproductive age The genetic code for protein synthesis has not been altered in a gamete producing cell The mutation occurs in a body cell of the organism, resulting in cancer O The mutation results in a change in the amino acid sequence of the protein in a gamete producing cellBeing able to understand the relationship between DNA, mRNA, tRNA, ribosomes and proteins, is necessary for any researcher interested in gene therapy. Gene therapy is dedicated to correcting genetic defects by replacing mutated genes with wildtype versions. This can include complete removal and introduction of a working copy of the entire gene (using knock-outs and knock-ins) or removal of only the actual mutated nucleotide. Sickle Cell Disease is an example of a recessive disorder based on a single-point mutation: GAG becomes GTG, which encodes a new amino acid. One would only need to replace a single base to correct the disorder making it very attractive to gene therapy researchers. The mutant sickle cell allele is called HbS (for sickled hemoglobin) while the wt allele is HbA. Pretend that Arcel Kasongo, a masters student from Cambridge, is studying for an oral exam on gene therapy, and has an especial interest in the disorder since he comes from the Democratic Republic of Congo…Being able to understand the relationship between DNA, mRNA, tRNA, ribosomes and proteins, is necessary for any researcher interested in gene therapy.
