BIOB10H3 Lecture Notes - Lecture 2: Nitrogenous Base, Heredity, Deoxyribose
Document Summary
Able to make copies of themselves by growing and dividing. Cell biology: study of the structure, function and behaviour of cells. Organisms are very diverse: there are morphological differences, but on a molecular level there are fundamentally similar, e. g. molecular code that specifies organisms is similar. Parents have offspring that belong to the same species. Molecular code specifies the characteristics of this offspring. Heredity: passage of information from parent to offspring: or the passage of characteristic specifications from parent to offspring, within an individual, a cell making copies and dividing itself is also heredity. Life depends on the ability of cells to store, receive, and translate information. The cell can gather raw materials from the environment to construct a copy of itself with its hereditary information. Cells store information that is readable by the information handling machinery of cells so that it can be read, interpreted, and carried out: despite morphological diversity, this is similar across organisms.
