Unit 1 DNA & The Genome

Biology: DNA and the Genome (Higher)
In this Unit, learners will develop knowledge through study of DNA and the genome. The Unit covers the key areas of structure and replication of DNA, gene expression, and the genome. This Unit explores the molecular basis of evolution and biodiversity, while the unity of life is emphasised in the study of gene expression. This approach enables the development of both analytical thinking and problem solving skills in context. An understanding of gene expression, at the cellular level, leads to the study of differentiation in organisms. In addition, the Unit covers the evolution and structure of the genome and genomics, including personal genomics.
