Yankulov University of Guelph I synthesize pre-mRNA, what polymerase am I? a) DNA polymerase b) RNA pol III c) RNA pol II d) RNA pol I d) RNA pol I __________ is darkly staining and densely packed chromatin which is transcriptionally __________. a) euchromatin; inactive b) euchromatin; active c) heterochromatin; inactive d) heterochromatin; active c) heterochromatin; inactive Where is the c...

Core Promoter Elements ~~> TATA box = repetitive sequence of thymine and adenine Initiator (INR) = sequence of pyramidines like thymine and cytosine DPE = downstream promoter elements found along the DNA Common to have >1 promoter but not all of them CpG islands ~~> Sequences high in CG frequency. They are able to escape methylation which would lead to gene silencing. Demethylation would lead to over expression of genes. Regulatory Promoter Elements ~~> UAS and URS f...

Describe how H3Lys9me heterochromatin is formed ~~> H3Lys9me heterochromatin formation: Lys9 deacetylated by HDAC. Suvar39 then methylates lys9. Methylated lys9 is recognised by HP1 and then HP1 binds. HP1 has chromodomain - chromodomains often recognise and bind to methylated lys residues. Chromodomain on HP1 is specific for H3Lys9me (with di or tri methylated lys 9). Binding of HP1 is thought to compact nucleosome arrays as HP1s join together. What is gene expression? ~~> ...

Consensus sequences are described with IUPAC ambiguous nucleotide codes. What is a promoter? ~~> DNA sequence which RNA polymerase can bind to and transcribe the protein Prokaryotic promoters ~~> TATAAT -(10 region) 'Pribnow box' TTGACA - (-35 region) - two consensus sequences Prokaryotic RNA polymerase ~~> 1 RNA Polymerase makes all 3 kinds of RNA Composed of 5 subunits, four comprise the core enzyme What is the core enzyme? 2 | P a g e | © copyright 2024/2025 | Gr...

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...
