Document Summary
Specific dna sequences that can be used to identify individuals, characterize human populations, or identify other species (such as metho genomics which is dna from soil) Sequences of dna are passed down from one generation to another and only changes due to mutations. Determining parentage used to use blood type but only proves who is not the parent. Genetic profiling diseases and medical conditions. Polymer: large molecule built from many monomers of similar form. Helical form is most stable conformation because it is the lowest energy state. Contains a phosphate group, a sugar and a nitrogenous base. Adenine, guanine, thymine and cytosine complementary base pairing. Dna polymerase adds nucleotides to the end of pre-existing strands. ** errors in replication are a source of mutation. Fluorescent molecule called ethidium bromide uv light shone on it. Can separate dna molecules of diff sizes using gel electrophoresis (shape. How are genes inherited? and density is the same between.
