Final answer:
Interphase chromosomes in eukaryotic cells are not in a highly condensed state. Instead, they exist as euchromatin and heterochromatin, with the former being less dense and actively transcribed.
Step-by-step explanation:
Interphase Chromosomes in Eukaryotic Cells:
During interphase in eukaryotic cells, the chromosomes are in a decondensed state.
They are not visible as distinct structures under a microscope. Instead, the chromatin exists in two distinct regions: euchromatin and heterochromatin.
The euchromatin is less dense and contains genes that are actively transcribed, while the heterochromatin is tightly packaged and contains genes that are not expressed.
Therefore, the statement that interphase chromosomes represent the physical state of chromatin with the highest order of packaging is false.
