One question that constantly arises, however, is whether autophagic activity in dying cells is the cause of death or is actually an attempt to prevent it. Morphological and histochemical studies have not so far proved a causative relationship between the autophagic process and cell death.
AP endonucleases are divided into two families based on their homology to the ancestral bacterial AP endonucleases endonuclease IV and exonuclease III. [6] Many eukaryotes have members of both families, including the yeast Saccharomyces cerevisiae , in which Apn1 is the EndoIV homolog and Apn2 is related to ExoIII.
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 ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
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.

Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence. 3'-end Also three-prime end. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon is not attached to another ...
