Incubation of RNA in high pH solutions results in degradation of the RNA molecule. Draw the reaction mechanism of this alkaline hydrolysis process of RNA.
CHOOSE THE BEST ANSWER Why did Natural selection ultimately favor DNA over RNA as the primary information molecule of life on Earth? DNA can store more information than RNA. DNA can replicate faster than RNA. DNA is more nutritious than RNA. ODNA is more stable and has a lower mutation rate than RNA. DNA is requires less energy to maintain and reproduce than RNA. Question 6 CHOOSE THE BEST ANSWER A major difference between Prokaryotes and Eukaryotes is that eukaryotic...
Please, list the general reaction that is catalysed by RNA polymerase and why is Mg2+ important? (diagrams are acceptable)
7. Why is RNA less stable than DNA? b) it is subject to hydrolysis at high pH a) it is subject to hydrolysis at low pH it is subject to degradation by nucleases d) both a and c are reasons e) both b and c are reasons 8. Which of the following are NOT types of DNA damage? a) deamination b) depurination c) oxidative damage e) depyrimidination d) alkylation 9. What is the role of restriction endonucleases in molecular cloning?...
What is the importance of the 2′ hydroxyl group in the ribose sugar of an RNA molecule? Check all that apply. View Available Hint(s) Hint 1. Properties of an hydroxyl groupopened hint A hydroxyl group has the formula OH. Water, alcohols, carboxylic acids, and other hydroxy-containing compounds can be deprotonated owing to the high electronegativity of oxygen, resulting in a stable conjugate base. Hydroxy-containing compounds are also able to form hydrogen bonds, which lead to higher boiling and melting points...
Part A -Why is cDNA used in RNAseq? Because cDNA is more stable than RNA Because it captures all the genes expressed in a tissue or a cell Existing sequencing protocols are designed for sequencing DNA All the above are true Submit Request Answer Part B-Why do scientists measure gene expression? Because Gene expression is static, and the same gene is always expressed the same Because Gene expression realtes to changes in the genomic DNA Because Gene expression is dynamic,...
3. Which reaction describes why the pH is not 7 for the dissolution of MgF2 in water? A. Mg2+ + 4H2O = Mg(OH)2 + 2 H30+ B. Mg2+ + H2O = MgH2 + O2- c. F + H2O = HF + OH- D HF + H2O = F + H307
Explain why ICP-MS is more sensitive than ICP-AES. Please explain why, do not just compare them, thanks!
Describe why AES is more sensitive to temperature changes than AAS. (HINT: Think about what AES measures compared to AAS.) PLEASE DESCRIBE IN DETAIL
Which type of transcriptional termination requires formation of a stem loop secondary structure in the RNA? What is the primary factor involved in the termination of RNA synthesis? Is a new nucleotide added to a growing strand of RNA at the 3′ end? DNA and associated histones compose what molecule? Be able to use a codon table to give the sequence of amino acids from an mRNA sequence. I will give you an mRNA sequence; you will indicate how many...
