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.
Since a bit alone cannot represent enough data to be useful to humans, bits are grouped together, eight at a time, to form a byte. In other words, two bytes are equivalent to 16 bits, and three bytes the same as 24 bits. The more complex a document or application is, the more bytes are required to represent and store it in a computer. Prefixes Modern computers deal in very large amounts of bytes.
