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.
Some people use a space instead (4B4A 5700); in both cases the idea is readability. These groupings are also special. Four bytes (such as my 3 initals and the <null>) are called a word. A group of 4 hexademical digitsâwhich would be 16 bits longâis called a halfword.
