TAILIEUCHUNG - Lecture Molecular biology: Chapter 3 - Robert F. Weaver

Chapter 3 - An introduction to gene function. Chapter 3 outlines the three activities of genes and provides some background information that will be useful in our deeper explorations in subsequent chapters. This chapter presents the following content: Storing information, replication, mutations. | Molecular Biology Fourth Edition Chapter 3 An Introduction to Gene Function Lecture PowerPoint to accompany Robert F.

Storing Information Producing a protein from DNA information involves both transcription and translation A codon is the 3 base sequence that determines what amino acid is used Template strand is the complementary DNA strand that is used to generate the mRNA Nontemplate strand is not used in RNA transcription 3- Protein Structure Proteins are chain-like polymers of small subunits, amino acids DNA has 4 different nucleotides Proteins have 20 different amino acids with: An amino group A hydroxyl group A hydrogen atom A specific side chain 3- Polypeptides Amino acids are joined together via peptide bonds Chains of amino acids are called polypeptides Proteins are composed of 1 or more polypeptides Polypeptides have polarity as does DNA Free amino group at one end
