There are several methods of gene editing, including ________, the most widely used method.
djyliett [7]

There are several methods of gene editing, including CRISPR-Cas9 the most widely used method.

One of the most popular methods of gene editing currently is the use of CRISPR/Cas9.Genome editing relies on the production of site-specific double-strand DNA breaks (DSBs) and the subsequent endogenous repair through the error-prone non-homologous end-joining (NHEJ) or the error-free homology-directed repair (HDR) pathways.

CRISPR/Cas9 is a technique that allows for the highly specific and rapid modification of DNA in a genome, the complete set of genetic instructions in an organism. In comparison to other technologies CRISPR/Cas9 is reliable Due to the RNA-based nature of the system, CRISPR is the most flexible, scalable, and user-friendly of the gene-editing platforms.

Geologic plates move away from each other in a process called convergence. O True O False​
KengaRu [80]

two geological tectonic plates are moving towards each other, where one of this plate go in direction beneath the other plate. As they moved towards each other mountain chain can be formed in a situation whereby the two plates has the same density.

Hence, the best option is FALSE because it is in only "DIVERGENCE PROCESS " that the plates moves away from each other.
