How does alternative splicing differ from intron splicing? -
ANSWER -Alternative splicing - splicing and rejoining of
different regions of one primary transcript allowing more than
one kind of mRNA to be produced from a single primary
transcript.
Intron splicing- removal of non-coding regions, which does not
allow more than one mRNA to be translated
How does selective degradation play a role in regulation of
gene expression? - ANSWER -If proteins are degraded they are
not physically presents to influence gene expression
control elements - ANSWER -Noncoding DNA that serve as
binding sites for
transcription
factors
proximal control elements - ANSWER -control elements
located close to the
, RNA
promoter
distal control elements - ANSWER -control elements located
far from the RNA
promoter
general transcription factors - ANSWER -essential for the
transcription of all
protein-coding genes; associated with low levels of
transcription
Enhancers - ANSWER -Groups of control elements that
control rates of
transcription
activator proteins - ANSWER -increase transcription by
facilitating protein-to-
protein interactions or by binding to other
regulatory regions
Repressor proteins - ANSWER -Cause gene transcription to
decrease or completely cease by binding to DNA control
element regions or by blocking activator proteins
alternative splicing - ANSWER -Type of RNA processing that
involves the splicing and rejoining of different regions from one
primary transcript. Benefit = producing multiple mRNA
transcripts from one primary transcript.
