Translation elongation Study guides, Class notes & Summaries

BISC 440 cell and molec exam 2 questions and answers graded A+ Elongation factors check the accuracy of codon-anticodon pairing and increase the rate of translation RNA polymerase II requires general transcription factors to help position it correctly at the promoter Polyribosomes (complexes of two or more ribosomes) can be seen in the electron microscope. What is holding the ribosomes together? mRNA In eukaryotes, but not prokaryotes, ribosomes find the start site of tr...

BI 213 midterm 2 practice exam 79 Questions with Verified Answers What is the purpose of the TATA box found in eukaryotic promoters? A) It serves as a termination signal for RNA polymerase B) It sets the translation reading frame of the mRNA C) RNA polymerase II binds directly to the TATA box to initiate transcription D) It binds the first Met-tRNA for translation of the mRNA E) It is the binding site for general transcription factors that recruit RNA polymerase - CORRECT ANSWER E ...

NSG 531 Antibiotics Exam Questions with Correct Answers translation inhibitors - Answer-tetracyclines & macrolides drugs working on ribosomes are not very selective: more adverse effects tetracyclines - Answer-translation inhibitors bind to 30s block tRNA binding to mRNA which interrupts peptide elongation macrolides - Answer-translation inhibitors bind to 50s prevent the formation of peptide bonds between amino acids and prevent exit of nascent proteins from ribosome b...

NST 160 Midterm 1 2023 Questions with All Correct Answers 2 mechanisms that regulate AA translation - ANSWER elf2 kinases, mTOR why can't postprandial (after a meal) increases in protein synthesis be explained by increased AA concentration? - ANSWER 1. translational initiation but not elongation is accelerated by increased AA levels 2. removal of the essential AA leucine prevents the effects of AAs on protein synthesis 3. norleucine, which cannot be incorporated...

Genomics Midterm Exam Questions With Complete Solutions. DNA is a polymer composed of all of the following EXCEPT: a. nitrogenous base b. 5-carbon sugar c. codon d. phosphate group c codon = 3 nucleotide sequence Which of the nitrogen-containing bases are purines? a. adenine b. cytosine c. thymine d. guanine a, d cytosine and thymine are pyrimidines In a DNA sequence, adenine nitrogen base pairs with _________, while guanine pairs with _________. a. uracil, thymine b. th...

• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...

Describe the process of transcription. What are the starting molecules and the end products? - ️️Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule ...

AP Biology: Unit 6 Exam Latest Update Graded A+ 5 end and 3 end -5 end gets a modified nucleotide 5cap - 3 end gets a Poly-A-tail Avery, McCarty and Macleod Announced that the transforming substances was DNA Bacterial transformation Transformation is the process by which foreign DNA is introduced into a cell. Transformation of bacteria with plasmids is important not only for studies in bacteria but also because bacteria are used as the means for both storing and replicating plasmi...

Gene Expression - Process by which DNA directs protein synthesis; transcription and translation Transcription - Synthesis of RNA under DNA direction; Produces mRNA; use same language Translation - Synthesis of polypeptide under RNA direction; Nucleic acids and amino acids use different language, Ribosomes are site of translation Triplet code - Series of three-nucleotides (make amino acids) Template strand - Provides template for RNA transcription mRNA base triplets - Codons Direction codo...

MCB 3020C Module 2 Exam Review Questions and Answers 2024. *Anything denoted in red are extra important takeaways 1. What is the function of the Z ring in binary fission? A. It forms a contractile ring at the septum => Made up of FtsZ (tubulin homologues) molecules important for bacterial septation B. It controls the replication of DNA => Replisome contains DNA replication machinery C. It separates the newly synthesized DNA molecules => ParA polymerizes/depolymerizes to attach t...
