PCB 3063 EXAM 1 STUDY GUIDE SOLUTIONS



genome - ANSWER✔✔-complete set of genetic instructions for any organism; encoded in nucleic acid


transmission genetics - ANSWER✔✔-encompasses the basic principles of heredity and how traits are

passed from one generation to the next


molecular genetics - ANSWER✔✔-concerns the chemical nature of the gene itself: how genetic

information is encoded, replicated and expressed


population genetics - ANSWER✔✔-explores the genetic composition of groups and individuals of the

same species (population) and how that composition changes over time and space


model genetic organism - ANSWER✔✔-organisms with characteristics that make them particularly useful

for genetic analysis and about which a tremendous amount of genetic information has accumulated


pangenesis - ANSWER✔✔-ancient greeks developed; concept suggested that specific pieces of

information traveled from various parts of the body to the reproductive organs from which they are

passed to the embryo; was proven incorrect

from preexisting cells and the cell is the fundamental unit of structure ad function in living organisms. ;

was proven correct


germ plasm theory - ANSWER✔✔-weismann; holds that the cells in the reproductive organs carry a

complete set of genetic information that is passed to the egg and sperm ; was proven correct


menedelian inhertiance - ANSWER✔✔-traits are inherited according to specific pinrciples proposed by

mendel- was proven correct


two types of basic cells - ANSWER✔✔-eukaryotic and prokaryotic

intracellular membranes; can be unicellular or multicellular
