75. Unique or non-repetitive sequences are found once or a few times in the genome.
76. A chromosome territory is the region of nucleus preferentially occupied by a particular chromosome.
77. Alignment of sister chromatids is performed by cohesin
78. Euchromatin is loosely packed transcriptionally active chromatin.
79. DNA gyrase and TopoII regulate supercoiling of DNA.
