This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
AP site formation can also be caused by various base-modifying chemicals. Alkylation, deamination, and oxidation of individual bases can all lead to the weakening of the glycosyl bond, so exposure to agents that cause those modifications can encourage AP site formation. [2] Ionizing radiation can also lead to AP site formation. Irradiated ...
An open textbook is a textbook licensed under an open license, and made available online to be freely used by students, teachers and members of the public.Many open textbooks are distributed in either print, e-book, or audio formats that may be downloaded or purchased at little or no cost.
The Infinite sites model (ISM) is a mathematical model of molecular evolution first proposed by Motoo Kimura in 1969. [1] Like other mutation models, the ISM provides a basis for understanding how mutation develops new alleles in DNA sequences.
Site saturation substitutes each of the 20 possible amino acids (or some subset of them) at a single position, one-by-one. In molecular biology, a library is a collection of genetic material fragments that are stored and propagated in a population of microbes through the process of molecular cloning.

The enzyme DNA-(apurinic or apyrimidinic site) lyase, also referred to as DNA-(apurinic or apyrimidinic site) 5'-phosphomonoester-lyase (systematic name) or DNA AP lyase (EC 4.2.99.18) catalyzes the cleavage of the C-O-P bond 3' from the apurinic or apyrimidinic site in DNA via β-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.
