Meet Paul, a potato farmer. Every year
he watches as half his average dies
because of one tiny pest, the Colorado
potato beetle. These beads will severely
damage the leaf, preventing the plants
from photosynthesizing, causing them to
wither and die. Paul has tried
everything, but his farm is being
overrun. Doesn't have to be so because
Nobel Prize on discovery has opened the
door to revolutionary solution.
Scientists found a way to protect pulse
crops using a naturally occurring
molecule called doublestranded RNA.
These are encoded with a sequence
identical to that of an mRNA sequence in
the body of the beetle. After the potato
has been engineered to produce this
dsna, the beetle eats it. Inside the
beetle's body, a natural protein called
dicer fragments the long dsrna strand
into small pieces called sirna. These
doublestranded sRNA are then attached to
a group of molecules called the RAC
complex. Inside this complex are
specific molecules that separate the SNA
strand into the guide strand and the
passenger strand. The guide strand is
used for a sequence to copy and hunt
down the beetle's own matching mRNA
sequences. The blueprints for the
central proteins. The complex then binds
the guide strand to the complimentary
sequence and makes a single cut in the
binding mRNA section. This deactivates
the mRNA which signals the cell to
rapidly destroy the entire strand. This
occurs on a massive scale throughout the
beetle's body. In its vital geostance,
the beta can no longer create the
proteins it needs to survive. This leads
to a gradual failure of its systems. If
you think about it, it kind of sounds
like a Trojan horse. The potato holds a
special surprise inside it. And when the
beetle accept this gift, the potato, it
accept a surprise with it which comes
back and destroys it. This technique is
called RNA interference and is still an
active area of research. This beats
traditional pesticides that could pose
chemical risk to everyone involved. What
