MCB 2050 MT Questions With Complete Solutions
A gene regulatory sequence which function as the binding site
for basal transcription factors to recruit RNA polymerase 2 and
initiate transcription is called? Correct Answers Promoter
A subunit within the general transcription factor ? binds to the
Tata box during transcriptional activation Correct Answers
TFIID
According to the reading what particular feature of molecular
hybridization makes it a powerful tool in molecular biology?
Correct Answers Highly specific
An activator functions by binding what element to increase
transcription in a gene specific manner Correct Answers
activators bind enhancers
an element that is a regulatory DNA sequence that binds
transcription factors to increase transcriptional activation energy
in gene specific manner Correct Answers Enhancer
Antibody generated against mouse IgG constant domain and
produced in rabbits is referred to as? Correct Answers Rabbit
anti-mouse
binds the pre-initiation complex Correct Answers TFIIH
chemical crosslinkers, give example Correct Answers Arrange
molecules in fixed close proximity.
Fromaldehyde
, Chromatin Immunoprecipitation (ChIP) Correct Answers can
determine if proteins can bind to a particular region of DNA in
the chromatin of living cells
Chromatin Immunoprecipitation (ChIP) is another technique
commonly used to study gene regulation transcription factors -
DNA interactions in (vitro/vivo). Correct Answers VIVO
