In 2020, Jennifer Doudna won the Nobel Prize in chemistry for her work on the CRISPR-Cas9 gene-editing technology that allows ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

DNA replication and repair mechanisms constitute the foundation of genomic integrity, ensuring that genetic information is faithfully duplicated and maintained across cell generations. Replication ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA . A few years ago, the advent of technology known as CRISPR was a major breakthrough in the ...

DNA replication is the fundamental process by which cells duplicate their genetic material before division. Initiation occurs at defined origins where a hexameric helicase unwinds the double helix, ...

There are many health problems that can be traced back to errors in the genetic code. There are also many potential benefits to genetic engineering outside of healthcare. Nature has already found ways ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then ...

The genetic alphabet contains just four letters, referring to the four nucleotides, the biochemical building blocks that comprise all DNA. Scientists have long wondered whether it's possible to add ...
