I think observation and measurable.
<span>Proteins that are involved in the packaging of eukaryotic chromosome into "beads" called nucleosome are histones.</span>
A nucleosome is a segment of DNA wound in sequence around eight proteins called histones. Together the DNA and the histones form "beads"
A nucleosome is the basic unit of DNA packaging in eukaryotic cells.
<span>In cup fungi, the spore-producing asci are located on the inner surface of the mature fruiting body. Spores are released in a cloud when the asci break open. Gilled mushrooms have basidia located on the gills on the underside of the cap. The spores are dropped from the gills when mature.</span>
