It can take from 5 to10 plus years to earn a PhD in sociology, but I think 7 years about average including coursework, prelims and the dissertation.
Enzyme hydrolysis Enzyme hydrolysis Enzymatic hydrolysis process converts pre-treated substrate to monomeric sugars, which could be further converted to ethanol or other value-added chemicals. An ideal enzymatic hydrolysis process is expected to yield maximum conversion of substrate to sugars at high consistency within reasonable time with least enzymatic input.
Restriction enzyme: An enzyme from bacteria that can recognize specific base sequences in DNA and cut the DNA at that site (the restriction site). A restriction enzyme acts as a biochemical scissors. Also called a restriction endonuclease.
