Principles of Heredity. Gregor Mendel, an Austrian monk, is considered to be the father of genetics. (Ref.1) Genetics is the science that studies patterns and mechanisms of heredity and Mendel laid the foundations of this field with his seminal work on garden pea plants. If you wish to focus your biological curriculum, you may choose from one of four areas of emphasis: neuroscience, the study of the nervous system; genomics, an area of genetics focusing on the sequencing and analysis of an organism’s genome; cell and molecular biology, how cells function at the molecular level; or ecology and environmental ... With the context in mind that Brandon wrote, enrichment means an increased presence or expression of a given RNA (in this case siRNAs), and depletion, a decrease. Biology is the natural science that studies life and living organisms, with the other life sciences its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals , while botany is the study of plants. The central dogma of molecular biology was first enunciated by Francis Crick in 1958 and re-stated in a Nature paper published in 1970. The Central Dogma of Genetics is that: DNA is transcribed to RNA which is translated to protein. Protein is never back-translated to RNA or DNA; and except for retroviruses, DNA is never created from RNA. Introduction Biology genetics test pdf.
