Smallest human chromosome
WebbFor example, the shortest human chromosome contains 4.6 x 10 7 bp of DNA (about 10 times the genome size of E. coli ). This is equivalent to 14,000 µm of extended DNA. In its most condensed state during mitosis, the chromosome is about 2 µm long. This gives a packing ratio of 7000 (14,000/2). WebbInterphase: (1) Includes karyokinesis and cytokinesis. (2) Some time called resting phase, is the preparatory phase for division in which cell undergoes growth and DNA replication in an order. (3) Is the shortest phase in which biomolecules are synthesised very fast. (4) Includes 5% duration of the cell cycle. 15.
