DNA

An examination of the structure of the huge polymer, DNA starts this unit. From there, the focus turns to a consideration of the three essential functions of DNA, namely replication, protein synthesis (transcription and translation) and three types of gene mutations. Complete rationales for each function are included along with useful examples. A special feature of this unit is an interactive Genetic Code used for determining amino acid sequences. The unit is supported by original artwork and labeled diagrams and contains many questions such as short answer and multiple choice that are linked to their answers for self-testing. It also includes sets of written answer questions to help build one’s understanding of the concepts presented. The unit features an interactive Glossary with hundreds of contextually explained terms.

DNA is extracted from Biology 12 Study Guide, which is the sixth edition of a student study guide written to match the curriculum of British Columbia. The concepts presented are applicable to the biology curricula of other educational jurisdictions as well.
