Question
A 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 has located the coding strand of cDNA from the AML gene that she wants to target for her RNA interference: ATG CCC GGT AAT CGC TTA TGC CTC. What will be the sequence of her siRNA?
a
AUG CCC GGU AAU CGC UUA UGC CUC.
b
TAC GGG CCA TTA GCG AAT ACG GAG.
c
CTC CGT ATU CGC TAA GGU CCC GUA.
d
UAC GGG CCA UUA GCG AAU ACG GAG.
2)
RNAi works by inteferring with mRNA. Esther decides to design her RNAi strand using genomic DNA (gDNA) information. What is your opinion on her approach?
a
Smart move! You got this, girl!
b
It would be better if she designs the RNAi to bind to Drosha, since it is meant to bind to the transcript in the nuclease to avoid it from being transported to the cytoplasm where the ribosomes are.
c
She needs to work with gRNA not gDNA.
d
She needs to work with cDNA not gDNA since mRNA lacks introns unlike gDNA; this is necessary since it is meant to interfere with mature, spliced mRNA.

- A 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) Given her knowledge of RNAi, what type of RNA will Esther use to target the murine AML gene? a piRNA. b circRNA. c lncRNA. d siRNA. 2) In order for Esther’s RNAi to work, the small RNA pieces have to interact with another molecule. What molecule does she hope it will bind to? a DUH! It will bind to the DNA strands of the AML gene and knock it out! b It will bind to tRNA, which will block attachment of the amino acids needed to make the AML protein. c It will bind to circRNA, which will increase its longevity. d It will bind to the…arrow_forwardplease help me with this questionarrow_forwardPlease answer botharrow_forward
- In your earlier research for this case study, you have discovered that nucleotides 1591-1593 (in the cDNA sequence, not CDS) are deleted in many CF patients causing a ΔPhe508 mutation in the CFTR protein. What are these three nucleotides in the CFTR cDNA sequence? Hint: you can copy the cDNA sequence from NCBI (with numbers) into a word processing program (e.g. Microsoft Word) to study the sequence or use a free DNA software program available by searching the internet.arrow_forwardOne procedure of obtaining cDNA from mRNA is by using oligo(dT) primers. What are oligo(dT)s? Why does using them make sense based on the processing (or modification) of precursor mRNA to get mature mRNA?arrow_forwardHelp me figure out how I should interpret and read these graphs. We are looking to see whether the m6a acceptor mutant will have an impact on splicing. Just need a detail breakdown thanks. I am presenting at journal club and need help interpreting will the goals in mind. We are currently conducting experiments to understand how the splicing of circE7 relates to the splicing of linear E6*I. Goal is to determine whether the mutation impact splicing. Trying to understand whether m6A will impact splicing. Sm should impact splicing ratio. My PI stated that the results show that it inhibited linear splicing and promoted backsplicing. I need a detailed explanation for the entirety so I can understandarrow_forward
- When the cDNA was sequenced by the Sanger method utilizing ddCTP, the following products were obtained: Tetranucleotide Hexanucleotide Nonanucleotide Decanucleotide Dodenucleotide Octadecanucleotide Nonadecanucleotide 21-nucleotide 6c. What is the sequence of the bases in the mRNA coding for the peptide above?

To test whether and how Cas9 might be able to target DNA cleavage, researchers developed an in vitro assay. One of the first steps was to purify the Cas9 protein from Streptococcus pyogenes and several orthologs. The description of the figure states: SDS-PAGE analysis of purified Cas9 orthologs. Cas9 orthologs were purified as described in Supplementary Materials and Methods. 2.5 ug of each purified Cas9 were analyzed on a 4-20% gradient polyacrylamide gel and stained with SimplyBlue Safe Stain. Answer the following questions based on this information and the figure. a. What is the experimental/research question and state a hypothesis related to this question. b. What is the approach of the figure and provide a description of techniques…arrow_forwardPrior to the publication of the article from which this assay comes from (picture), the Cas9 endonuclease was known to be involved in CRISP RNA (crRNA) maturation, but the mechanism by which Cas9 participates in targeted DNA disruption was unknown.

- The new vaccines use messenger RNA (mRNA) in order to trigger the body into mounting an immune response against the viral particles of SARS-CoV-2. SARS-CoV-2 is the name of a type of coronavirus that causes the disease, Covid-19. As you know, mRNA carries the instructions to build proteins. What specific proteins does the mRNA in the adult Moderna vaccine code for?arrow_forwardTryptophan synthase is one of the enzymes synthesized from the trp mRNA. In wild-type E. coli, the trp mRNA has a short half-life, but the tryptophan synthase half-life is much longer. To investigate how changes to the stability of the enzyme or its mRNA affect enzyme activity, two strains of E. coli were engineered. Strain A stabilizes the trp mRNA and strain B rapidly degrades tryptophan synthase. The wild-type, A, and B strains were grown in a medium with glucose as the sole carbon source. After several generations, tryptophan was added to all three cultures and tryptophan synthase activity was measured periodically. Note: Evaluate each condition as a simple model, where changes in the stability of trp mRNA or tryptophan synthase do not elicit secondary effects in the cells. Select the statements that describe the expected change in tryptophan synthase activity after the addition of tryptophan. In strain B, since both the trp mRNA and tryptophan synthase are rapidly degraded, the…arrow_forwardplease help me with this problemarrow_forward
