Some autoimmune diseases show a positive correlation with dramatically decreased expression of histone deacetylase 9 (hdac9, an enzyme that removes acetyl groups from histones). why would the decreased expression of hdac9 cause immune cells to produce inflammatory genes at inappropriate times?

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

wha is what i will use to get my free points

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

is it multiple choice?
