Gene editing for the production of “Super Dad” cattle

Image rights JonOatley Image description According to scientists, the genetically modified goats are “proof in principle” Scientists have produced gene-edited animals that they say could serve as “super-fathers” or “surrogate sires”. The pigs, goats, cattle and mice produce sperm, which carry the genetic material from donor animals. The researchers used a high-tech gene editing tool to turn off a male …

For the first time, CRISPR gene editing was used on squid

For the first time, the innovative CRISPR gene editing method was used on squid. This marks a milestone in the scientific study of these creatures – and opens up many new areas of potential research. CRISPR enables very precise, fast and inexpensive DNA processing. Simply put, the ingenious molecular workings of the method are often described as something that allows …

A new understanding of the CRISPR-Cas9 tool could improve gene editing

The 3D structure of a basic editor, consisting of the Cas9 protein (white and gray), which binds to a DNA target (blue-green and blue helix) that is complementary to the RNA guide (purple), and the desaminase proteins (red and pink ). who exchange one nucleotide for another.

The modified CRISPR gene editing tool could improve the therapies for HIV and sickle cell disease

Credit: CC0 Public Domain City of Hope researchers may have found a way to sharpen the fastest, cheapest and most accurate gene editing technology, CRISPR-Cas9, to more successfully cut out unwanted genetic information. This improved cutting ability could someday accelerate potential therapies for HIV, sickle cell disease and possibly other immune diseases. "Our CRISPR-Cas9 design may be the difference between …
