d) all of these
e) none of these
A scientist used a transgenic strain of C. elegans into
which a gene (gfp) for a green fluorescent protein had
been introduced. He injected some worms with
double-stranded RNA complementary to coding
sequence of the gfp gene. The figure below shows the
worms without (a; left) and with (b; right) ds gfp RNA.
a
(-) ds gfp RNA
_(+) ds gfp RNA
a) Explain these results .
b) The scientist conducted another experiment in which
he injected double-stranded RNA complementary to
the introns and promoter sequences of the gfp gene.
What results would you expect with this experiment?
Explain your answer .
What is an open-reading frame?
a) An unknown gene
