http://cyberbridge.mcb.harvard.edu/mitosis_4.html WebDec 14, 1990 · Current analyses of genes often focus on relatively short stretches of DNA and consider chromatin conformations that incorporate only a few kilobases of DNA. In interphase nuclei, however, orderly transcription and replication can involve highly folded chromosomal domains containing hundreds of kilobases of DNA.

WebChromosomes condense and become visible by light microscopy as eukaryotic cells enter mitosis or meiosis. During interphase (G1 + S + G2), chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes). In G1, each chromosome is a single chromatid. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/the-process-of-meiosis/
