Chlorine, potassium chloride, manganese (II) chloride, and water are to be

Case
Ubiquitination is a post-translational modification used to regulate many
processes: the cell cycle, cell death, protein function, protein degradation by
the proteasome. Deubiquitinating enzymes remove ubiquitin from proteins,
with implications in the same processes. Some viruses use deubiquitinating
enzymes as a way to hijack the host cell.
Question
What type of small molecule would combat such a virus? Answer -
Deubiquitinating enzyme inhibitor

DNA strands are wound around histones to form nucleosomes when forming
chromosomes. Post-translational modification of histones affects the chromatin
structure. One common post-translational histone modification is histone
acetylation, where a positively charged lysine residue on the histone is
acetylated and loses its charge.
Question
How will histone acetylation affect chromatin structure and transcription?
Answer - Relax chromatin, increase transcription
