Which statements about the modification of chromatin structure in eukaryotes are true?
DNA is not transcribed when chromatin is packaged tightly in a condensed form
Methylation of histone tails in chromatin can promote condensation of the chromatin
Acetylation of histone tails in chromatin allows access to DNA for transcription
Acetylation of histone tails is a reversible process
All of the above are true statements of the modification of chromatin structure in eukaryotes

Topic: muscle tissue Briefly explain how the structure of the
tissue allows for the function of the tissue. Be sure your post is
relating specific aspects of its structure to function. This
discussion is not asking students to simply describe structure and
then describe function. Rather, it is asking students to relate
structure to function.
1) When chemical methods of cell modification are used, how does
the construct get into the cells? Briefly (in no more than 2
well-written sentences) explain the process using one particular
type of chemical method as your example.
2) Briefly (in no more than 2 well-written sentences)
hypothesize about how EITHER gene augmentation strategies OR gene
inhibition strategies could be useful for treating a particular
disease with gene therapy.
How
does structural modification lead to understanding of how structure
influences activity and pharmacokinetics for extension, isosteres,
simplification, and chirality?
