A friend of yours who works at a biotechnology start up company has computationally designed three new proteins that she thinks might be able to prevent and possibly reverse cancers if they could be expressed/transported in the right location in human cells. If this works, the company will be worth billions and everyone who works there will be rich. Not to mention curing cancer…
The plan is to use a genetically modified, harmless virus to deliver the DNA genes for these three proteins. This should result in the transcription of mRNA and translation of the three proteins. The trick is getting the proteins to go to the right places in the cells so they can interact with the right cellular pathways.
The first protein is a transcription factor that binds to DNA and should shut down transcription of cancer promoting genes by binding to their promoters. The second is a protein that interacts with electron transport chain proteins to reduce the output of reactive free radicals in…

Select one:
A. DNA replication.
B. the flow of genetic information from DNA to proteins.
C. how genes are passed from parent to offspring.
D. the unique set of genes in an individual.

- Which of the following statements about genes is incorrect? Select one: O a. During fertilization, both the sperm and the ovum contribute genes to the resulting fertilized egg. b. Genetic differences can result from changes in the DNA called mutations. O c. Genes correspond to segments of DNA. d. Under normal circumstances, each chromosome contains precisely one gene. e. Many genes contain the information needed for cells to synthesize enzymes and other proteins.arrow_forwardIn general, all mutations can be considered harmful, because most genetic systems are already optimized to work correctly and efficiently. A. True b. False; mutations are considered harmful only if they have a direct effect on the ability of cells to synthesize DNA c. False; some mutations are harmful, and some are considered beneficialarrow_forwardIn the novel Chromosome 6, by Robin Cook, a biotechnology company genetically engineers individual bonobos (a type of chimpanzee) to serve as future organ donors for clients. The genes of the bonobos are altered so that no tissue rejection takes place when their organs are transplanted into a client. What genes would need to be altered for this scenario to work? Explain your answer.arrow_forward

These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! (answer both questions) question 1: A mutation in what type of gene is probably the cause of this unusual situation? Why? question #2: would you expect the proteins that make the spines to be different in the mutant fish compared to a wildtype fish. Why or why not?arrow_forward1.
