Which of the following statements concerning eukaryotic chromatin is true.     Histones have an overall negative charge.     Euchromatin is more condensed then heterochromatin.     After replication nucleosomes are made up of a mixture of old and new histone proteins.     Euchromatin is associated with the centromere and telomere regions.     Heterochromatin are regions of active transcription.
