Processing of the nascent mRNA may begin beforeits transcription is complete.c. Processing takes place in the cytoplasm.d. Termination is accomplished by the use of a hairpinloop or the use of the rho factor.e. Many RNAs can be transcribed simultaneously fromone DNA template
I've attached the table of transcription ans translation for a DNA and Bees work, Genes A and B are exons while C is an intron. Gene A has a silent mutation and Gene B has a nonsense mutation. Please answer the below for me The 3 genes code for different proteins: • Gene A = protein essential for stinger • Gene B = DNA replication enzyme • Gene C = fuzzy hair protein Do you think it matters which protein is mutated? Is one protein more important than another? How would you try to help the bees stay healthy using the information from the mutations?
1) Antibiotic-resistance is one of the gravest dangers to the world’s medical system. As a result, Dr. Jhon Peῆa decides to apply for a research grant from the NIH to investigate novel targets for antibiotic treatment in his lab. Most bacteria have developed resistance to counter the effects of the current crop of antibiotics, which largely target the cell wall, plasma membrane, or ribosomes. Dr. Peῆa’s team has instead been investigating bacterial transcriptional sites and all of his students are asked to attend a group Zoom meeting to discuss ideas to put into the grant. The lab technician, Jazmin, wonders if anyone thought of blocking the entrance way to the ribosome, the translator of mRNA? What does the rest of the lab think? a Considering the grant is for transcriptional targets, this makes no sense. b This makes perfect sense since the bacterial ribosome has a different structure than the eukaryotic ribosome, which everyone learns in Intro Bio in their…

Dr. Peῆa’s team has instead been investigating bacterial transcriptional sites and all of his students are asked to attend a group Zoom meeting to discuss ideas to put into the grant. 1) Dr. Wilhem, his post-doc, mentions that heat-sensitive RNA pol mutants found in yeast might be worth exploring to see if they could be genetically engineered into E. coli. He reckons that anyone who is sick from a bacterial infection typically develops a fever so this would activate their destruction. a GREAT IDEA! b SUCKY IDEA! Yeast are eukaryotic so their RNA pol binds to a different site…

Dr. Peῆa’s team has instead been investigating bacterial transcriptional sites and all of his students are asked to attend a group Zoom meeting to discuss ideas to put into the grant. 1) One of Dr. Peῆa’s doctoral students, Marisol, finds out there are multiple mutant forms of U ribozymes using BLAST. Remember that U ribozymes make up part of the spliceosome . Will this news be of any benefit? a YES! LOF in any of the U ribozymes will halt splicing, which is necessary before a transcript can be translated. b NO! Bacteria are capable of alternative splicing so they will use a…
