Scientists have made a leap in genetic engineering by pushing elephant cells into an embryonic-like state. This marks a major ...

A biotech company recently announced that it's implanted another pig kidney into a human recipient. Here's what to know.

These are created by transferring nuclei containing DNA from human cells into animal eggs that have had almost all of their genetic information removed. The resulting embryos are more than 99% ...

Protecting animals against environmental changes, poachers, and other dangers is vital yet challenging work. And in recent ...

Chemical modification of DNA or of chromatin-associated proteins, particularly histones, has a major influence on chromatin structure and gene expression. In animal cells, DNA can be modified by ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

a cell that contains DNA that is mostly elephant, but a little bit mammoth. If that cell is then used to create an embryo and eventually an animal, the result will be a hybrid animal with DNA ...

Most animal cells possess a nucleus, cell membrane, cytoplasm and mitochondria. The nucleus contains the genetic material (DNA) of the organism and controls the cell’s activities. The cell ...
