BIOL 2050 Lecture Notes - Lecture 1: Dna Replication, Nuclear Membrane, Sister Chromatids
Document Summary
The study of inherited variation in populations of individuals. Forces, such as environment, that result in changing gene frequencies over generations. The study of genetic events at the molecular level. Genetic technology has developed faster than the legal and social consensus. 2. 1 prokaryotic and eukaryotic cells differ in a number of genetic characteristics. Prokaryote is a unicellular organism with a relatively simple structure. Eukaryote has a compartmentalized cell structure with componenets bounded by intracellular membranes; eukaryotes may be unicellular or multicellular. Prokaryotes include at least two fundamentally distinct types of bacteria: Major difference between p and e cells is that a euk has a nuclear envelope, which surrounds the genetic material to form a nucleus and seperates the dna from the other cellular contents. In prokaryotes cells, the genetic material is in close contact with the other components of the cell. Another fundamental difference between the two lies in the packaging of their dna.
