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.
Bytes (8 bits). 1  0. 1 bytes: A single yes/no decision (actually 0.125 bytes, but I rounded). 2  1 byte: One character. 3  2 bytes: 4  5 bytes. 5  10 bytes: One word (a word of language, not a computer word). 6  20 bytes: 7  50 bytes: 8  100 bytes: Telegram; two punched computer (Hollerith) cards. 9  200 bytes: 10  500 bytes:
