- Give a brief description of how RNAi works in cells specifying the molecules involved?arrow_forwardA doctoral student in biology, Esther Mensah, is reviewing primary literature over RNAi interference as part of her literary research for her proposal on decreasing the amount of abnormal white blood cell growth associated with acute myeloid leukemia (AML) using a murine (mouse) model. She is being provided with 10 AML mice courtesy of her mentor. Can you help her out with her proposal? 1) Esther’s eventual goal is to design 20-26 bp RNA pieces that can bind to mRNA of AML and test it in a murine model. Of the choices below, which seems like the first step necessary to get her research off the ground? a) Make sure there is similarity between the murine AML gene and the human AML gene using a Clustal Omega alignment. b) BLAST the human version of the AML gene in NCBI. c) First, see if there is an existing mouse AML gene accession on NCBI to work with since that would negate the necessity to produce her own saving much time and money. d) Design the RNAi she will use for…arrow_forwardDescribe in detail the process of RNAI including the major protein involved.

- Several common antibiotics affect some strains of bacteria's ability to carry out transcription and/or translation. For example: Rifamycin inhibits prokaryotic RNA polymerase Chloramphenicol blocks the transfer of the peptide from the P to A site. a) For each of these drugs, identify at what point it could affect the process of DNA->RNA->protein. Be as specific as possible. b) Why do you think these drugs kill bacteria but spare animal cells? (Hint: remember bacteria are prokaryotes)arrow_forwardRNAi is currently being tested as a therapeutic tool for genetic diseases and other conditions. Consider the following: cystic fibrosis caused by loss of function of the CFTR gene, HIV infection, and cancer caused by hyperactivity of a growth factor receptor. Which of these may be treatable by RNAi, and which not? Explain your reasoning.arrow_forwardInhibiting the reverse transcriptase of HIV is a common method for treating HIV infections. a) The HIV reverse transcriptase has two separate functional domains. One domain has polymerase activity. What type of activity do you think the other domain would have?arrow_forward
