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.
In many computer architectures, a byte is the smallest addressable unit of memory. For example, an 820 megabyte (MB) hard drive holds a nominal 820 million bytes of data. Due to massive increases in storage capacity over time, there are now eight additional units of measurement following the byte.
