New Discovery: Scientists Find Better DNA Cutting Tool Than CRISPR
CRISPR Changed Science – But Now There’s Something New
CRISPR is a famous tool that helps scientists cut DNA. It comes from bacteria and lets experts change genes in humans, animals, and plants. CRISPR cuts double-stranded DNA (DNA with two strands). It’s great for treating some diseases.But scientists always wanted a tool that could cut single-stranded DNA (DNA with just one strand). Now, researchers from INRS in Canada have found something brand new!
What Is Single-Stranded DNA?
Single-stranded DNA (ssDNA) is not as common as double-stranded DNA. But it’s very important. You can find it in some viruses and it helps in:-
Cell repair
-
DNA replication
-
Gene editing and sequencing
-
Medical and science technologies
Until now, no enzyme could cut only single-stranded DNA. This was a big problem for scientists.
Meet the New DNA Tool: Ssn Enzymes
A team led by Professor Veyrier at INRS has discovered Ssn enzymes, a group of special proteins. These enzymes can cut only single-stranded DNA at specific points.
They studied these enzymes in a bacteria called Neisseria meningitidis (this bacteria can cause meningitis). They found that the enzyme cuts DNA in the same spot again and again. This helps the bacteria swap genes and change over time.
Even better—scientists found thousands of similar enzymes! Each one cuts DNA in its own special place.
Why This Discovery Matters
This is big news for science and health! These enzymes can help with:-
Better gene editing
-
Faster and cheaper DNA tests
-
Improved ways to detect diseases
-
New treatments for infections
These tools may even help us fight harmful bacteria or viruses in the future.
A New Era in DNA Technology
This new tool goes beyond CRISPR. It gives scientists more control and more options when working with DNA.There is already a patent pending, so we may soon see these tools in hospitals, labs, and research centers around the world.
Final Words
Thanks to INRS scientists, we now have a powerful way to cut single-stranded DNA. This could bring amazing changes to medicine, science, and technology. CRISPR was just the beginning—this new tool is the future!
