It resolves abortive DNA ligation intermediates, formed either at base excision sites or when DNA ligases try to repair non-ligatable breaks induced by reactive oxygen species. Molecular pathology. Defects of APTX cause ataxia-oculomotor apraxia syndrome, and are a cause of coenzyme Q10 deficiency (COQ10D).
(A bit is a binary digit, either 0 or 1; a byte is 8 binary digits long): 1  If you counted all the bits in one petabyte at one bit per second, itâd take 285 million years. 2  If you counted one byte per second, it would take 35.7 million years. 3  It would take 223,000 DVDs (4.7Gb each) to hold 1Pb.
1 A byte is an ordered set of 8 bits having given values 2 A byte can have any one of 256 values, depending on the values (e.g., 0 or 1) of each of its 8 bits. o Examples of different values of a byte are: Ã¼ 00000000 (binary number for 0) Ã¼ 00000001 (binary number for 1)
