How did humans evolve brains capable of complex language, civilization, and more? The answer could lie in exceptional DNA. Scientists at UC San Francisco have found that parts of our chromosomes have ...

the macronucleus and the micronucleus (Figure 1). The micronucleus is the germ-line nucleus that contains five normal pairs of chromosomes, but it is transcriptionally inactive under most ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

A recent Trump executive order defines sex based on gamete size. But the order oversimplifies genetics, hormones and reproductive biology.

It’s not clear why these backups have evolved. The new Y chromosome sequences could spell change for metagenomics research, which involves sequencing microbial genomes. Human DNA contaminants often ...

An individual’s growth and development is affected by the genes they inherit from their parents. An example of a human chromosome mutation is when a child inherits an extra copy of chromosome 21.

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...

The research focused on parts of chromosomes known as human accelerated regions (HARs), which have evolved ... HARs make up a big portion of the 1% difference, which can lead to dramatically different ...
