B) a post-transcriptional mechanism to regulate mRNA C) transcriptional control of gene expression. (D) post-translational control that activates certain proteins. E) a eukaryotic equivalent of prokaryotic promoter functioning. 24) If you were to observe the activity of methylated DNA, you would expect it to Al be unwinding in preparation for protein synthesis. B) induce protein...

I need help with question 18. The answer is D. Thanks for any help in advance. yupo cellular organelles. B) Unlike eukaryotes, prokaryotes require no initiation or elongation fa C) Extensive RNA processing is required before prokaryotic transcript DN Translation can begin while transcription is still in progress. El Translation requires antibiotic activity. 18) Which of the following is not true of a codon? A) It never codes for more than one amino acid. B) It consists of three nucleotides....
Question 1 Match the term with the best definition or description; most topics relate to the regulation of gene expression. General type of protein which will increase transcription rates when it attaches to a site A. Factor connected to a particular gene - B. Co-repressor C. Enhancer D. Promoter E. Structural F. Intron G. Activator H. Operator I. Basal transcription J. Glucocorticoid receptor K. Sigma factor L. Mediator M. Inducer N. TATA box O. Repressor The rates of mRNA produced...
Please help with 1-16!!! (two pictures are attached) Thanks! Transcription . Although both prokaryotes and eukaryotes put a cap and a tail on the mRNA, only eukaryotes have introns that have to be spliced out. (T/F) 2. The poly A tail on cukaryotic mRNA protects the RNA from rapid degradation in the cytoplasm. (T/F) 3. The polyA tail is added to eukaryotic mRNA immediatel after transport of the message from the nucleus. (T/F) 4. is usually a single stranded molecule....
Here is all the information and content! One of the questions which shows a double stranded sequence and asks for the mRNA sequence has not correct answer. It should be dropped. Anyone who majored in Bio can answer these 2nd-year biology multiple questions (only Q14 has more than one answer). Thanks a lot!!!!! Question This type of RNA does not participate in the splicing reaction, but is important for efficient functioning of the spliceosome. Not yet answered Marked out of...
