MIP 300 Final questions and answers graded A+ 2023/2024

MIP 300 FinalAerobic Respiration Pathways - correct answer 1) Glycolysis 2) TCA Cycle (w/ Intermediate Step) 3) Electron Transport Chain (ETC) -final electron acceptor is Oxygen Anaerobic Respiration Pathways - correct answer 1) Glycolysis 2) TCA Cycle (w/ Intermediate Step) 3) Electron Transport Chain (ETC) -final electron acceptor is NOT Oxygen Fermentation Pathways - correct answer 1) Glycolysis 2) Fermentation Pathway -final electron acceptor is pyruvate or a pyruvate derivative What is ppg? - correct answer -Peptidoglycan, the main structure of the cell wall of a bacteria (NOT in eukaryotes or archaea) -Backbone of alternating NAG and NAM carbohydrates RNA Synthesis: AGGA - correct answer AGGA is the Shine Dalgarno sequence, it is part of the leader sequence and allows the ribosome to align to RNA to translate protein AUG - correct answer -Start codon -Translation start site for mRNA -This translates to fMet protein-- BEFORE post translational modification, this is included in amino acid count. -It is NOT included when counting GTPs for bringing amino acids to tRNAs UAA, UAG, UGA - correct answer -Stop codon -Termination- translation stop site for mRNA -All codons after this point are part of the trailer sequence RNA Synthesis: -35 site - correct answer 5' TTGACA 3' -(35 nucleotide bases back from the +1 site, where transcription starts) -RNA polymerase RECONGNITION site -part of the promoter region RNA Synthesis: -10 site - correct answer TATAAAT -Pribnow Box -(10 nucleotide bases back from the +1 site, where transcription starts) -RNA polymerase BINDINGsite -part of the promoter region RNA Synthesis: +1 site - correct answer -where transcription starts -end of promoter region, mRNA starts here -NOT THE SAME AS AUG Polycistronic - correct answer A type of mRNA that can encode more than one polypeptide (gene) separately within the same RNA molecule -This is normal for bacterial mRNA -NO eukaryotes Monocistronic - correct answer A type of mRNA that only encodes for one gene in one RNA molecule -Happens in eukaryotes 3 Types of RNA - correct answer -rRNA: makes up ribosomes -tRNA: carries amino acids to ribosome during translation
