Suppose you have a 1-kb segment of cloned DNA that is suspected to contain a eukaryotic promoter including a TATA box, a CAT box, and an upstream GC-rich sequence. The clone also contains a gene whose transcript is readily detectable. Your laboratory supervisor asks you to outline an experiment. (1) determine if eukaryotic transcription factors (TF) bind to the fragment and, if so, (2) identify where on the fragment the transcription factors bind. All necessary reagents, equipment, and experimental know-how are available in the laboratory. Complete the outline of an experiment, which determines if eukaryotic transcription factors (TF) bind to the fragment. Assume all necessary reagents, equipment, and experimental how are available in the laboratory. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. For the band shift assay, two samples of the DNA fragment are analyzed by agarose gel electrophoresis: one sample is…
Proteins such as Dicer and RDE-R are involved in RNAi inactivation of target gene expression and are present in most eukaryotes. However, most eukaryotic cells do not naturally produce double stranded RNA. What is the most likely reason why these genes are evolutionarily retained in most eukaryotes? What are possible consequences of intron retention?
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…
Imagine that a colleague asks you to align a conserved spike protein-coding gene sequence from SARS-CoV2 virus (Severe acute respiratory syndrome-related coronavirus variant 2) to its homolog (i.e., equivalent spike protein-coding gene sequence) in the MERS virus (Middle East respiratory syndrome-related coronavirus). Which sequence type - nucleic acid (DNA or RNA), or protein - would you expect to exhibit the highest percentage of identities? Why?
Consider the mechanism of the enzyme RNase:  What would happen to the Km (i.e., would it increase, decrease, or stay the same) if the his12 was mutated to a lysine? Explain.  What would happen to the Kcat (i.e., would it increase, decrease, or stay the same) if the his12 was mutated to a valine? Explain.

RNA editing is a common process in the mitochondria of trypanosomes and plants as well as in chloroplasts, and in rare cases it occurs in higher eukaryotes. What is RNA editing, and what benefit does it demonstrate in the documented example of ApoB in humans?

These three RNA polymerases have different functions How might geneticists use α-amanitin as a tool in research? Propose a specific question that could be addressed using α-amanitin.
