Genetic Engineering Tools Crispr Revolutionizing Animal

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) has
transformed genetic engineering, particularly in animal models, by
offering precise, efficient, and cost-effective methods for gene
modification. Its impact is profound, with widespread applications in
creating genetically modified organisms to advance biomedical research.

In animal research, CRISPR enables the targeted knockout of specific
genes, the study of genetic diseases, and the creation of animal models
that better mimic human conditions. For example, in zebrafish, CRISPR
has been used with remarkable efficiency, achieving mutation rates as
high as 86% with minimal off-target effects (Hruscha et al., 2013). The
technology\’s precision and speed have revolutionized mouse model
development, where direct zygote injection of CRISPR components can
yield mutants with targeted genetic modifications in just one step (Qin
et al., 2016).

The introduction of CRISPR has significantly reduced the time and
resources needed to create genetically modified animals, improving the
efficiency of research. Methods like CRISPR-EZ, which involves
ribonucleoprotein electroporation of zygotes, have increased genome
editing efficiency to nearly 100%, cutting down the laborious steps of
traditional techniques such as microinjection (Chen et al., 2016).
Additionally, CRISPR\’s application extends beyond mice, with successful
gene modifications seen in larger animals like pigs (Polkoff et al.,
2020).

CRISPR’s ability to make targeted genetic modifications in animal models
allows researchers to explore hypotheses about gene function, disease
mechanisms, and potential therapeutic strategies. Its utility in
creating complex genetic modifications has further opened new avenues in
precision medicine and drug development (Miano et al., 2016).
