Homework Answers
Answer:
Clearly only one of the options talks about activation of cytotoxic cells creating an immune response against cancer. None of the other option mentioned immune system but only about genetic correction using CRISPER. So the correct answer is (a).
Give a thumbs up if you like the answer. Thank you

1. Viral integration into the cellular genome may convert a proto-oncogene into a transforming oncogene 2. Immunosuppressive drugs used to prevent graft rejection include drugs (like Imuran) that result in generalized suppression of all dividing cells and drugs that target T cells (like cyclosporine A) 3. IFNα has a direct antitumor effect, while TNFα has an indirect cytotoxic effect on tumor cells 4.Oncogenes are unique genes of a normal cell that only function to promote cell transformation. 5.

Write the letter of the correct answer on the first page. Control of entry into the cell cycle is essential. Unicellular eukaryotes that enter into it too soonyw have the necessary energy to complete it, leading to their demise, whereas in multicellular eukaryotes usually leads to cycle are controlled by proteins, problems with the genes that code for these proteins are a commorn source of error. These genes fall into two broad groups: 33 uncontrolled cellular division 32 Since the...
