Virus a noncellular genetic element that enlists a cell for its own replication, it has an extracellular state. A virus particle containing nucleic acid surrounded by protein and other macromolecular components is called virion

CELLULAR ADAPTATION Excessive physiologic stresses. Some pathologic stimuli. A new, but altered state preserving the viability of the cell

Definition gestational trophoblastic disease(GTD)is a group of disease originated from placental villose trophoblastic cells, including hydatidiform mole, invasive mole, choriocarci- noma and a kind of less common trophoblastic cell tumor in placenta

Notes LECTURE Biochemistry 9.17.04 ATP is both a unit of energy currency in a cell and a building block of RNA. Why? It is believed that early in evolution there were very few molecules around. Many key pathways are ancient, and trace their origin to the early stages of evolution of life on Earth. Incidentally, such pathways are usually highly conserved in modern organisms. This is probably because once
