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 is abbreviated with a B. (A bit is abbreviated with a small b.) Computer storage is usually measured in byte multiples. For example, an 820 MB hard drive holds a nominal 820 million bytes-or megabytes-of data. Byte multiples are based on powers of 2 and commonly expressed as a rounded off decimal number. For example, one megabyte (one million bytes) is actually 1,048,576 (decimal) bytes.
