More than 80% of early human embryos contain cells with an incorrect number of chromosomes—a phenomenon called aneuploidy.

A new tool generates and labels customized aneuploid cells in living tissue to observe the behavior of these cells in ...

Each human cell thus contains 46 chromosomes in 23 pairs. The gametes or ovum produced by the female ovaries and the sperm produced by the male testicles, however, contain only 23 chromosomes.

To Shakespeare's Hamlet, we humans are "the paragon of animals." But recent advances in genetics are suggesting that humans ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair.

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

“Just a few years ago, half of the human Y chromosome was missing ... Humans typically have a pair of sex chromosomes in each cell. People who are assigned male at birth have an X and a Y ...

Human artificial chromosomes (HACs) capable of working within human cells could power advanced gene therapies, including those addressing some cancers, along with many laboratory applications, though ...

Human cell types in two dimensionsImage ... of short bits of DNA chopped at random from a chromosome. The other was computers, which spotted overlaps between those sequences, and so patched ...

Chromosome 2 is the second largest of the 46 chromosomes found in human cells. Chromosome 2 spans 243 million base pairs and makes up around 8% of the total DNA present within our cells.

The research focused on parts of chromosomes known as human accelerated ... of HARs in artificial neurons derived from human and chimpanzee cell lines. The human and chimpanzee genomes are 99% ...

Human-accelerated regions (HARs) in chromosomes help human neurons grow multiple neurites ... The human neurons grew multiple neurites, or wiry projections that help the nerve cells send and receive ...
