Bio 99 Exam Questions With Complete Solutions
7 processes of protein concentration Correct Answers 1.
Transcription
2. Posttranscriptional processing
3. mRNA deg
4. Translation
5. Posttranslational processing
6. Protein deg
7. Protein targeting and transport
Acetylation Correct Answers Activating by HATs
Alpha function Correct Answers Regulation, binds promoter
elements
Anabolic Regulation, and why Correct Answers Repression, So
there is feedback inhibition
Beta function Correct Answers bind NTPs and interacts with
sigma, polymerizes RNA
Beta Prime function Correct Answers Binds DNA
Blocks initiation by binding to beta subunit Correct Answers
Rifampicin
Catabolic Regulation, and why Correct Answers Induction, so
there isn't any expression until the affector is present
, Cis acting elements Correct Answers DNA sequences near
genes
Components of a plasmid vector Correct Answers Selection
Marker, ORI, Gene of interest
DAB Funtions Correct Answers Recognizes promoter and
initiation of PIC assembly
Deacetylation Correct Answers Repressing by HDACS
Differences between transcription and replication Correct
Answers Txn is selective, one strand is a template, txn does not
need a primer, txn is more error prone
E Funtions Correct Answers Modulates Helicase
Elongation structure is made of Correct Answers RNAP, E, H,
and Negative or Positive Elongation Factor
Eukaryotic Promoter Motifs Correct Answers TATA Box, INR
(initiator element), DPE (Downstream promoter element), TFIIB
recognition element
Eukaryotic Transcription rules Correct Answers Must be
activated, Combination of larger txn factors needed, bind to
Core promoter, regulator sequences are up and down stream.
F Pol II Functions Correct Answers Target PolII and promoter,
Actual Polymerase
