- Transcription factors function in the nucleus. However, like (almost) all eukaryotic proteins,they are translated in the cytosol. Can you draw a visual to explain how transcription factor proteinsenter the nucleus from the cytoplasm? Can you also include a representation of relevant proteins and proteindomains to explain how these proteins reach their destination. Thank youWhat is the production of RNA called and what is the enzyme that catalyzes the process?What are the similarities and differences between the transcription process and the repli-cation processes?Concerning their biological function what is the difference between DNA and RNA? Is there any situation in which DNA is made based on a RNA template? If there is,explain with an example how it occurs and state the enzyme involved?What is the difference between plasma membrane and cell wall?Which of the following characterize RNA polymerase Il transcriptional termination in eukaryotes?

- Hydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds. Why is this a desirable feature for DNA? Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls. What happens to protein synthesis if a nonsense codon is inserted into the gene? Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations) Choose any pentapeptide composed of five different amino acids. List the amino acids. Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.Modifications of histone tails can: O repress the transcription of some genes affect chromatin structure affect the transcription of some genes in response to the diet or environment activate the transcription of some genes all of these choices are correct The ferritin gene encodes an IRE (Iron-response element) within the 5 UTR (untranslated region) of the MRNA Considering what you know about eukaryotic translation, the IRE-BP (Iron Response Element Binding Protein) is bound to the IRE in the 5'UTR. you would expect: O That the presence of the IRE-BP would enhance translation. That the presence of the IRE-BP would have no effect. That the presence of the IRE-BP would block translation I don't remember enough about the IRE-BP or transiation to guess. 3 Assuming that the trait represented by the filled symbols in the pedigree is an inherited trait due to a single gene with alleles A and a, what mode of inheritance does the pedigree shown suggest?Shown below is an eukaryotic gene.
