genome - *answers *complete set of genetic instructions for any organism; encoded in nucleic
acid
transmission genetics - *answers *encompasses the basic principles of heredity and how traits
are passed from one generation to the next
molecular genetics - *answers *concerns the chemical nature of the gene itself: how genetic
information is encoded, replicated and expressed
population genetics - *answers *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 - *answers *organisms with characteristics that make them particularly
useful for genetic analysis and about which a tremendous amount of genetic information has
accumulated
pangenesis - *answers *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
inheritance of acquired characteristics - *answers *ancient Greeks lead to this; which traits
acquired in a person’s lifetime e become incorporated into that person's hereditary information
and are passed on to offspring; ex. musical ability ; was proven incorrect
preformationist - *answers *miniature organism reside in sex cells; thus all traits are inherited
from one parent; which was proven to be incorrect
blending inheritance - *answers *proposed that the traits of offspring are a blender, or mixture
of parental traits; proved to be incorrect
, PCB 3063 EXAM 1
cell theory - *answers *Schleiden and Schwann proposed; all life is composed of cells, cells only
arise from preexisting cells and the cell is the fundamental unit of structure ad function in living
organisms. ; was proven correct
germ plasm theory - *answers *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
Mendelian inheritance - *answers *traits are inherited according to specific principles proposed
by Mendel- was proven correct
two types of basic cells - *answers *eukaryotic and prokaryotic
gene - *answers *fundamental unit of heredity; an inherited factor that helps determine a trait;
often defined at the molecular levels as a DNA sequence that is transcribed into an RNA
molecule
alleles - *answers *genes that come in forms of
genes confer - *answers *phenotypes
genetic information is carried in - *answers *DNA and RNA
mutations - *answers *changes in genetic information that can be passed from cell to cell or
from parent to offspring
genetic information is transferred from - *answers *DNA to RNA in protein
repliecated chromosomes separate through - *answers *the process of mitosis and meiosis
