Heinrich Wilhelm Gottfried von Waldeyer-Hartz was a professor of anatomy and histology who coined the word "chromosome" in 1886. Waldeyer, noting the ability of thread-like structures in the nucleus to be stained by the dye fuchsin, named them "chromo"...

The bacterial or prokaryotic chromosome differs in many ways from that of the eukaryote. The term "eukaryote" comes from the Greek and means "true nucleus." Eukaryotic cells have a double membrane (the nuclear membrane)...

Chromosomes are microscopic units containing organized genetic information, located in the nuclei of diploid and haploid cells (e.g., human somatic and sex cells), and are also present in one-cell non-nucleated organisms (unicellular microorganisms)...

A chromosome banding pattern is comprised of alternating light and dark stripes, or bands, that appear along its length after being stained with a dye. A unique banding pattern is used to identify each chromosome and to diagnose chromosomal...

Chromosomes are organized structures of DNA and proteins that are found in cells. Chromosomes contain a single continuous piece of DNA, which contains many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound...

A rare genetic variation dramatically raises the risk of developing autism, a large study showed, opening new research targets for better understanding the disorder and for treating it.Research into the causes of autism has focused on genetic causes because so many families have multiple children...
