Chromosome, Eukaryotic
The deoxyribonucleic acid (DNA) of eukaryotic cells carries the blueprint for the biosynthesis of cellular
proteins
and the control of cellular assembly and regulation. If all the DNA in a single human cell were stretched out straight and the strands representing all the chromosomes laid end-to-end, they would extend for well over 1 meter (3 feet). This meter of DNA must fit into a
nucleus
whose diameter is on the order of 10
microns
(10
–
