DNA Polymerase Study Guide Test. DNA Polymerase - CORRECT ANSWER Enzyme that assembles nucleotides into a new DNA strand DNA Polymerase I - CORRECT ANSWER DNA repair and some replication. Highest concentration DNA Polymerase II - CORRECT ANSWER DNA repair. Middle concentration DNA Polymerase - CORRECT ANSWER Have 3'-5' exonuclease; proofreading ability - keeps mutation rate below a certain level. Can only polymerize in a 5'-3' direction. Can only add nucleotides to an existing ...

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...

Ch. 5 Define metabolism and describe the fundamental difference between anabolism and catabolism -Metabolism is involved with the buildup and breakdown of macromolecules within a cell; these chemical reactions provide energy and create substances that sustain life -Catabolism: breaks down complex molecules; provides energy and building blocks for anabolism; EXERgonic -Anabolism: uses energy and building blocks to build complex molecules; ENDERgonic Ch. 5 Identify the role of ATP as an intermedi...

BIO 111 FINAL EXAM QUESTIONS AND ANSWERS LATEST 2024/2025 (100% CORRECT) What is the first mRNA processing step? - ANSWER 5' capping Different mRNAs are made from the same initial pre-mRNA by ________. - ANSWER alternative splicing RNA transcription begins at a ________. - ANSWER promoter ________ protect(s) the pre-mRNA molecule. - ANSWER the 3' poly-a tail The process of pre-mRNA splicing removes ________. - ANSWER introns Spliced ________ differ in their exons. - ANSWER mRNAs Identif...

promoter region for mRNA transcription, describe it - TATA sequence (TATA box) help attract RNA polymerase In prokaryotes what is needed for the RNA polymerase to bind to the promoter - Sigma factors Sigma factors bind with RNA Polymerase to form - RNA polymerase holoenzyme and now has the ability to target the promoter region of bacterial DNA In eukaryotes DNA polymerase can not bind directly to the promoter region so it requires - Transcription factors

FRNSC 420 - EXAM 3 PRACTICE QUESTIONS AND ANSWERS (100% PASS) electrophoretic mobility shift assay (EMSA) - Answer️️ -demonstrates if a protein is bound to DNA - fragment is placed in non-denaturing polyacrylamide gel (native PAG) to keep protein associated to DNA - DNA/protein complex moves much slower in the gel due to added molecular weight (an electrophoretic mobility shift) - will appear higher in the lane compared to free DNA - migration depends on mobility of the protein; dif...
