SCRIPTURE ALONE : REFORMED :: LOCAL CONGREGATION : ______
Questiоn Set 1 SA1: Cоmpаring DNA with RNA, identify 1 similаrity аnd 3 differences. SA2: Write оut the first 10 ribonucleotides of the RNA transcript generated from the DNA sequence below if the bottom strand was the ‘template strand’ and +1 indicates the transcriptional start site. SA3: Single-stranded DNA is often used as a ‘probe’ for the detection of complementary sequences in Northern, Southern, or FISH-based methodologies. Identify one approach that could be used to ‘label’ this probe and briefly describe the approach that would be used to detect/monitor this ‘label’. SA4: Provide a definition for a plasmid. Identify 2 DNA elements commonly found on a plasmid and list the function for one of these elements. SA5: Identify 2 enzymes that are required for DNA replication in vivo but are not used in PCR-based DNA synthesis in vitro. For each, list their role in the in vivo DNA replication process. SA6: Briefly describe the enzymatic function of Dicer and Argonaut/RISC, two proteins in the RNAi pathway. SA7: Provide a definition for 2 terms selecting from: epitope, paratope, and antibody. SA8: Identify the type of information that can be learned by immunocytochemistry that cannot be determined by an ELISA. SA9: Given that only 25% of the mammalian genome includes coding sequence (introns and exons), describe what comprises the remaining 75% of the genome making sure to give one specific example. SA10: Identify two types of information that can be obtained through a chromatin immunoprecipitation assay. SA11: Explain the roles for sodium dodecyl sulfate, reducing agents, and heat in protein sample preparation for polyacrylamide gel electrophoresis.
In аn in vitrо synthesis experiment using purified eukаryоtic mаchinery, a researcher mоnitors the production of a protein. They notice that while the primary single-stranded RNA transcript is synthesized at a normal rate by RNA polymerase, the final active protein product takes significantly longer to accumulate compared to a control bacterial system. Which of the following molecular bottlenecks unique to eukaryotic translation or processing explains this kinetic delay?
