Big Idea 3: Living systems store, retrieve, transmit and respond to information essential to life processes.

Enduring understanding 3.A: Heritable information provides for continuity of life.

       Essential knowledge 3.A.1: DNA, and in some cases RNA, is the primary  source of heritable information.

                       e. Genetic engineering techniques can manipulate the heritable information of DNA and, in special cases, RNA. 

          To foster student understanding of this concept, instructors can choose an illustrative example such as: 
              •  Electrophoresis 
            •  Plasmid-based transformation 
              •  Restriction enzyme analysis of DNA 
              •  Polymerase Chain Reaction (PCR)

          f. Illustrative examples of products of genetic engineering include: 
              •  Genetically modified foods 
            •  Transgenic animals 
            •  Cloned animals 
              •  Pharmaceuticals, such as human insulin or factor X

Learning Objectives: 
LO 3.1 The student is able to construct scientific explanations that use the structures and mechanisms of DNA and RNA to support the claim that DNA and, in some cases, that RNA are the primarysources of heritable information. [See SP 6.5]

LO 3.2 The student is able to justify the selection of data from historical investigations that support the claim that DNA is the source of heritable information. [See SP 4.1]

LO 3.3 The student is able to describe representations and models that illustrate how genetic information is copied for transmission between generations. [See SP 1.2]

LO 3.4 The student is able to describe representations and models illustrating how genetic information is translated into polypeptides. [See SP 1.2]

LO 3.5 The student can justify the claim that humans can manipulate heritable information by identifying at least two commonly used technologies. [See SP 6.4]

LO 3.6 The student can predict how a change in a specific DNA or RNA sequence can result in changes in gene expression. [See SP 6.4]
