Each time a cell divides, a small section of each chromosome's protective cap—the telomere—is worn away. Most cells use an ...

By Nancy Lapid (Reuters) -Insulin-producing human pancreas cells can be manufactured with 3D printers, researchers reported ...

Norgen’s Cells and Tissue DNA Isolation 96-Well Kit (Magnetic Bead System) enables the extraction of genomic DNA from a variety of animal tissues and cell samples.

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 amazing job of this, copying genetic material ...

Radiation and pressure at these depths can damage DNA, leading to mutations and cell death. However, the deepest-living animal has an extraordinary system for repairing its genetic material.

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

There are more than 10,000 samples here, everything from skin to feathers. Curator Marlys Houck said, "When I was freezing cells from the northern white rhino, there were 50 living.

Using 'fission yeast', a single-celled organism that mirrors many of the inner workings of human cells, the research team ...

The colors are arbitrary, but I've used greenish-blue for plasma membranes and red or purple for DNA for many years. It's a generalized animal (including human) cell, with no specializations and ...

Only the cells that become germ cells retain the bonus DNA and pass it on to the next generation. How and why this feature evolved remains largely mysterious, though biologists first spotted it a ...

Macquarie University researchers have discovered a naturally occurring protein found in human cells plays a powerful role in repairing damaged DNA—the molecule that carries the genetic instructions ...

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.
