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 bit can take a value of 0 or 1. A byte is made up of 8 bits which is large enough to contain a single character. For example the character 2 would be equivalent to 00000010 when represented in bits. A Kilobyte is equivalent to 1024 bytes. A Megabyte is equivalent to 1024 Kilobytes. A Gigabyte is equivalent to 1024 Megabytes.
