info needed during RNA editing comes most directly from
enzymatic activity which destroys transforming principle
DNA lacks a free hydrozyl group of the __-_____ atom of its sugra.
Initiation of transcription does not require a _______.
What would be the consequences of a four-nucleotide deletion mutation in the middle of the first exon of a protein-coding gene?
A reading frameshift would occur. All codons (and thus amino acids) downstream of the codons in which the deletion occured would be different, including the stop signal.
Explain how antisense RNA would interact with RNA normally made by the gene, and how this would interfere with protein production.
Antisense RNA would bind to the normal RNA from a gene because it would be antiparallel and complementary. The double stranded RNA woud not be able to be translated, so the protein encoded by the gene would not be produced.
A linear chromosome which lacks a telomere at one end will
Be unstable and ultimately degraded
In vitro, missing
not necessary for RNA polymerase to recognize the promoter of a bacterial gene?
Origin of replication
Reverse the numbers and keep the same sequence of bases, but switch them with their complementary pairs
six exons, five introns
Alternative RNA processing
NOT on a mature RNA molecule
production of polypeptides that are not entirely encoded by DNA?
Which DNA strand would denature at the highest temp?
The one with the lowest temp of AT and highest temp of GC
All DNA polymerases synthesize new DNA by adding nucleotides to the _______ of the growing DNA chain.
which rna gets translated
Upstream of the start site
any amino acid encoded by stop?
activates an activator
which sequence of letters?
If a mutation prevents the formation of the antiterminator 2+3 loop in the trp operon, what would be the effect?
Info needed during RNA editing comes mostly fom
