The loss of heterozygosity and chromosomal alterations were frequently observed on human chromosome 6 in cancers. In this study, we analyse the relative RNA levels between the parental breast ...

Cytologists had been studying chromosome behavior since the late 19th century. Why did it take until 1956 to figure out the correct human chromosome number, thanks to Joe Hin Tjio and Albert Levan?

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.

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

Some ancient Homo sapiens genomes contained even more—6% or so—so it looks like ... so that it wouldn't work with human genes ...
