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.
A byte consists of 8 bits and is typically used to represent a single logical character. As each of the 8 bits can contain either of two binary values (1 or 0) the total number of combinations in any byte is therefore 2*2*2*2*2*2*2*2 = 2**8 = 256. The literal character for any particular byte value can vary depending on the Code being used by the computer.
