WebApr 9, 2024 · New, reversible CRISPR method can control gene expression while leaving underlying DNA sequence unchanged by Whitehead Institute for Biomedical Research WebGene knockdown is an experimental technique by which the expression of one or more of an organism 's genes is reduced. The reduction can occur either through genetic modification or by treatment with a reagent such as a short DNA or RNA oligonucleotide that has a sequence complementary to either gene or an mRNA transcript.
