None of these are TRUE Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin.arrow_forward
