Phosphorylation
Acetylation
Splicing
What is NOT a characteristic of SMC proteins?
Provide scaffolding for the chromosome
Hinged
Hold 30 nm solenoid structures
Form octagonal structures
Which of the following correctly matches a replication protein to a function?
Helicase - unwinding of supercoil
DNA polymerase III - lagging strand synthesis
DNA polymerase I - removing RNA primers
DNA clamp - hold ssDNA
Which of these is a function of telomerase?
Extension of the 5' end
Using DNA as a template
Degradation of DNA
Extra telomere elongation in stem cells

5' degradation
Which of these descriptions is characteristic of RT PCR?
Using fluorescent DNA dyes on an oligopoly probe to track amplification
Using Reverse Transcriptase to generate cDNA for PCR
Requires careful execution for hybridization
Initiation occurs at the 5' end
Plasmids are...
Circular RNA molecules
A mechanism for horizontal gene transfer
Found in only bacteria
Noncoding regions of DNA
According to which strand of DNA is RNA synthesized?
Template strand, RNA generated from 5' to 3'
Hair strand, RNA generated from 5' to 3'
Coding strand, RNA generated from 3' to 5'
Template strand, RNA generated from 3’ to 5’
Match the non-coding RNA to its function
Regulatory RNA - ribosomal structure
miRNA - transcription
tRNA - amino acid movement
rRNA - regulation
What provides the energy for ribosomal assembly?
NADPH oxidase
ATP hydrolysis

Which is an accurate statement for Helix-turn-helix?
HTH is not found in Hox proteins
HTH interacts with many different sequences
HTH is incorporated into different types of proteins and inserts into the DNA major groove
Two HTH structures can generate different regulatory outcomes and be covalently connected to reduce binding
Which is the most accurate description of the CRP protein's role in the context of the Lac repressor?
CRP binds to the promoter region when in presence of allolactose
CAMP binds to CRP and to a sigma factor and binds to the promoter
Presence of the CRP dimmer prevents induction
CRP isn't a part of the mechanism for the Lac repressor
