Which statements about the modification of chromatin structure in eukaryotes are true?

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

Normal gene order for a particular chromosome is ABC*DEF (where * is the centromere). An inversion changed the gene order to AD*CBEF. If an individual is heterozygous for the inversion (has one normal chromosome, and one with the inversion), show how the two chromosomes will pair in meiosis. Then show the chromosomes that will result if crossing over occurs in the inversion. Please draw a picture

6. During mitosis cells use changes in the chromosome apparatus to accurately separate their chromatid pairs between two cells. A. Please explain (and considering making a diagram) of how the spindle microtubules change across the process of mitosis. Please explain how chromosome attached microtubules change across mitosis and add those to your drawing. B. Please explain where and how changes in polymerization of microtubules drive these changes and how motor proteins function in this process. C. Please EXPLAIN HOW cells...
