CRISPR interference (CRISPRi) is a genetic perturbation technique that allows for sequence-specific repression of gene expression in prokaryotic and eukaryotic cells. [1] It was first developed by Stanley Qi and colleagues in the laboratories of Wendell Lim , Adam Arkin, Jonathan Weissman , and Jennifer Doudna . [ 2 ]
CRISPR repeats typically range in size from 28 to 37 base pairs (bps), though there can be as few as 23 bp and as many as 55 bp. [80] Some show dyad symmetry, implying the formation of a secondary structure such as a stem-loop ('hairpin') in the RNA, while others are designed to be unstructured.
CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / (crisper), refers to a clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.
The CRISPR process, a 2013 breakthrough in biology, provides a way of controlling the basic genetic processes of life. In addition, the film documentary considers several relevant questions including, How will this new gene-editing ability change our relationship with nature ? and, What will this new gene-editing ability mean for human evolution ?
A 19-year-old woman’s breasts stunningly grew from a B cup to a triple G in the six months following her Pfizer COVID-19 vaccination in what researchers are calling a first-of-its-kind case ...

Diagram showing type I-F CRISPR-Cas system, as well as inhibition mechanisms of three type I-F anti-CRISPRs. Type I-F CRISPR complex is made of 60 crRNA nucleotides and nine Cas proteins (the protein type is specified by the numbers 5,8,7,6). AcrF1 goes to Cas7f, preventing target DNA access to the crRNA guide.
