WebbOne of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells. Although it's not known exactly what causes this process to begin, scientists now know that it begins many years before symptoms appear. Webb6 nov. 2008 · Two UCSD biologists announced the discovery of a human protein last week that rewinds single-stranded DNA into its normal double-stranded form, potentially preventing critical genes — such as those responsible for genetic disorders — from forming. Previously, only proteins that unwound DNA were known to exist. DNA is a …
