Building blocks of all organisms
Stronger trait--hides recessive trait
control center of cell
Weaker trait--hidden by stronger trait
Organism made from one single cell (bacteria, amoeba)
Organism made from more than one single cell (plants, animals, fungi)
Thin fibers in nucleus. Contain genes.
Tiny segments of chromosomes. (About 25,000 per regular human cell.)
(Deoxyribonucleic acid) Material genes and chromosomes made up of.
Model used to predict possible traits in offspring.
DNA accidentally damaged or changed so that the genetic message carried by that gene is changed.
Doctors or scientists purposefully change an organism's genes.
Male and female parts combine to form offspring.
Way unicellular organisms make more of themselves--no female and male parts involved.
