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.
The alphabet is 26 bytes long. A byte is made up of 8 bits which is essentially just a true/false or on/off flag for computers expressed as the numbers 0 (false) and 1 (not false). For example, the letter âaâ looks like this in binary: 01100001. All those zeros and ones tell the computer to print an âaâ on the screen.
