Scientists have created a new technique that can assess how mutations in the genome influence the packaging of DNA in cells. The genome is massive, and has to be carefully wrapped around proteins so ...

Researchers found that approximately one in 40 human bone marrow cells carry massive chromosomal alterations without causing any apparent disease or abnormality. Even so-called normal cells carry all ...

A vast mosaic of cells, some that are identical and some that are slightly different, make up the human body. Knowable Magazine You began when egg and sperm met, and the DNA from your biological ...

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, ...

Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells ...
