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.
We investigate various enzyme and substrate related factors affecting the efficiency of hydrolysis including the effect of substrate accessibility, cellulose crystallinity, effect of hemicellulose and lignin removal, lignin-enzyme interactions, and the effect of degree of synergy between various enzyme components in the cellulase enzyme mixture.
Nuclease, any enzyme that cleaves nucleic acids. Nucleases, which belong to the class of enzymes called hydrolases, are usually specific in action, ribonucleases acting only upon ribonucleic acids (RNA) and deoxyribonucleases acting only upon deoxyribonucleic acids (DNA).
