BCHM 4360 Exam II Questions and Answers 100% Pass What are the three steps of translation? - Correct Answer️️ -initiation, elongation, termination True or False: The transcription bubble is just as big as the replication bubble. - Correct Answer️️ -False, replication bubble is much larger because it requires two machines at once. When does transcription officially start? - Correct Answer️️ -when RNA Polymerase binds to the promoter What is the first base to be transcribed kn...

Lesson Plan: Title Transcription Part II: What happens to the initial (premRNA) transcript made by RNA pol II? Objectives  Explain how the transcript generated by RNA polymerase II (the pre-mRNA) is processed to become mature mRNA, using the sequence signals identified in Module 2.  Use the genome browser to analyze the relationships among: 1. pre-mRNA 2. 5’ capping 3. 3’ polyadenylation 4. splicing 5. mRNA Pre-requisites  Modules 1 and 2  Define pre-mRNA as the RNA ...

DNA → RNA → protein Ans-Explain the central dogma of molecular biology. RNA polymerase Ans-DNA can be transcribed into RNA by the enzyme translated Ans-Following post-transcriptional processing, the resulting messenger RNA (mRNA) can be read by the ribosome (a ribozyme, with both RNA and protein components). This transcript is _____________ into protein, which can perform various functions in the cell DNA Ans-contains two strands of nucleic acids antiparallel to one another 5'...

BIO 345 Exam 1 Module 2 Questions and Answers 100% Pass Point mutation - substitution of a single base Silent mutation - different/wrong base but codes for same amino acid, no effect on protein's structure Missense mutation - results in a different amino acid being incorporated into the resulting protein; effect depends on how chemically different the new amino acid is from the wild-type amino acid Nonsense mutation - codes for premature stop codon; converts a codon encoding an amino...
