Document Summary
15. 2 understand the concept of base pairing as it relates to the double-helix structure of dna. 15. 4 explain the technology of polymerase chain reaction (pcr) and how it applies to forensic. 15. 1 name the parts of a nucleotide and explain how they are linked together to form dna. Dna is double stranded in the shape of a double helix. Composed of dna surrounded by other material, mainly proteins. Polymer: substance composed of a large number of atoms arranged in repeating units. Nucleotide: unit of dna consisting of one of four bases attached to a phosphate. 15. 2 understand the concept of base pairing as it relates to the double-helix structure of dna o o. Specific pairing of base awith tand base gwith cin double-stranded dna. Any base can follow another on a dna strand. Order in which the bases a, t, g, and c are arranged defines the role and function of a dna molecule.
