Histones/poly(A) question

[Marci Swede]

Some histones messages do become Poly-A. For example, histone 2A varients 
whose synthesis is s-phase independent (ie H2A.Z variants) jave poly-A 
messages.  These histones have been identifed in organisms from flies to 
pombe (but not cerevisiae) and tetrahymena.
