In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations ...

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such ...

Macquarie University researchers have discovered a naturally occurring protein found in human cells plays a powerful role in ...

DNA repair: A look inside the cell's 'repair café' Date: November 21, 2024 Source: Hubrecht Institute Summary: New research sheds light on how cells repair damaged DNA. For the first time, the ...

The approach, called DNA microscopy, uses simple chemical reactions essentially to map a cell’s interior, highlighting the contents and indicating exactly where everything can be found.

The technology could zero in on one spot in a cell’s genome, and then either snip out or insert new DNA. Dr. Shendure and his colleagues set out to use CRISPR to record a cell’s history.

A new class of drugs that combine artificial DNA structures with antibodies could make immunotherapies even more targeted—all you have to do is fold over and over again. In a study published Aug ...

But those cells have a formidable challenge. The average dividing cell must copy—perfectly—3.2 billion base pairs of DNA, about once every 24 hours. The cell’s replication machinery does an ...

Sometime between the embryo’s growth from seven cells to 32, huge chunks of DNA had vanished. The scientists then watched nematode embryos develop under a microscope. As the cells grew and replicated ...

They showed that mitochondria in the sperm's precursor cells did contain DNA, along with an important protein called mitochondrial transcription factor A (TFAM) that maintains and protects that DNA.
