What effect would inhibitors of histone deacetylases have upon transcription? Group of answer choices They would increase transcription by making the chromatin more compact They would increase transcription by making the chromatin less compact They would decrease transcription by making the chromatin more compact They would decrease transcription by making the chromatin less compact

Explain how plasma membrane proteins that start to be translated in the cytosol are then targeted to the ER during translation. I am looking for two things that are required here.

Can I please have help with this question,thank you!

1st answer choices: yes, no 2: yes, no 3:increase, decrease 4: a lot of mRNA or very little mRNA 5: less mRNA, more mRNA, or the same amount of mRNA

Before the next elongation cycle can take place at a ribosome, the peptide chain of the peptidyl-tRNA has to be transferred to the ___ site and the deacylated tRNA has to move to the ___site.   Question 46 options:   A, P   P, A   A, E   P, E   there is no peptidyl transfer happening during protein translation

Please offer an explanation for the correct answer

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?

Which of the following characterize RNA polymerase Il transcriptional termination in eukaryotes? Endonuclease cleavage of the RNA transcript and 5' to 3' exonuclease activity a protein known as Ratl None of the provided answers, transcriptional termination occurs in prokaryotes. Recognition of the transcriptional stop codon by a release factor. Hairpin structure formation on the newly synthesized RNA molecule which disrupts the DNA-RNA hybrid at a poly-U RNA sequence Binding of the Rho protein.

The diagram shown represents the coding strand of the myosin gene. Mutations in myosin can lead to muscle defects during development. Using what you know about how mutations can affect transcriptional and post-transcriptional regulation, match the results shown on the Northern (mature mRNA) to the mutations shown. The N lane shows the size and amount expected for non-mutated myosin mRNA. All samples were loaded at the top (-) side of the gel. Part 1. Which lane or lanes on the gel could be the result of mutation A? --4 ТАТАА AUG UAA Only known regulatory region TSS Mutation B: Mutation C. A: 5-base 20 nucleotides 3 nucleotides deletion deleted changed N 1 2 3 4 5

S # 3 Question Here is the sequence of an mRNA molecule: GUC/GGG/CUC/AGA/GAA What is the protein sequence that would be made from this mRNA sequence? The slash marks ("/") shown in the above sequence are so that you can read the sequence easier. The slash marks that are shown between the blanks below are to help you keep your place in the protein sequence.
