In the biology lab, you observe animal cells under a microscope. in one slide you see the nucleus with two nucleolus areas of compact chromatin. the value in packaging dna in tighter forms of chromatin is for

1 - To regulate and protect DNA during transcription: The highly compacted chromatin is not accessible to transcriptional enzymes. Therefore only the region that is unwinded will be accessible for transcription or repair.

2 - Mobility and protection of the DNA molecule during mitosis: The DNA compaction protects chromosomes from breakage during mitosis
