Select all that apply.

1. Some forms of chromatin modification can be passed on to future generations of cells.

2. Deacetylation of histone tails in chromatin loosens the association between nucleosomes and DNA.

3. Methylation of histone tails in chromatin can promote condensation of the chromatin.

4. Acetylation of histone tails in chromatin allows access to DNA for transcription.

5. Acetylation of histone tails is a reversible process.

6. DNA is not transcribed when chromatin is packaged tightly in a condensed form.
