CRISPR — Cas9 uses an RNA
molecule to
target DNA, cutting to a known, user - selected
sequence in the
target genome.
But oligomers are large and somewhat clumsy
molecules, and they occasionally bind to cellular components other than the
target sequence.
Through the combination of CRISPRs and RNA - guided endonucleases, such as Cas9, («Cas» stands for CRISPR - associated), bacteria are able to utilize small customized crRNA
molecules (for CRISPR RNA) to guide the
targeting and degradation of matching DNA
sequences in invading viruses and plasmids to prevent them from replicating.
In RNAi, double - stranded RNA
molecules target a messenger RNA with a corresponding
sequence and cause it to be chewed up, thus preventing the messenger RNA from making its protein.
It involves adding all reagents in a single reaction: CRISPR - Cas12a and its RNA
targeting sequence (guide RNA), fluorescent reporter
molecule and an isothermal amplification system called recombinase polymerase amplification (RPA), which is similar to polymerase chain reaction (PCR).
If the beetle does evolve to resist an RNA
molecule, he says, geneticists could easily launch a new assault: just «slide the
sequence over» by a few letters or
target several genes at once.
Although this intriguing possibility remains theoretical, the similarities in the amino acid
sequences of NGF and insulin are not great enough to result in any similarity of function: the two
molecules have completely different
target cells and biological activities.
Jennifer Doudna and Samuel Sternberg used a combination of single -
molecule imaging and bulk biochemical experiments to show how the RNA - guided Cas9 enzyme is able to locate specific 20 - base - pair
target sequences within genomes that are millions to billions of base pairs long.
In the presence of a donor DNA
molecule with homology to the
target region, the CRISPR system can also be used to introduce specific nucleotide modifications into a
sequence of interest.
Cas9 uses short RNA
molecules, known as guide RNAs, to
target the protein to a specific
sequence within cellular DNA.
These phage libraries have tremendous diversity, so you can use them to find very unique antibody protein
sequences that
target specific
molecules within disease pathways,» says Coyle.
