Mon. 8.3.09 Lecture 1: Introduction to Molecular Biology A cell is a fundamental unit of living matter. All living things are made up of cells. The fundamental feature of a cell is its ability to reproduce successfully. All cells contain the same three macromolecules- DNA, RNA, and Proteins- to carry out their fundamental properties of life. In all living cells, genetic information flows from DNA → RNA → Protein. o RNA Synthesis – Transcription o Protein Synthesis – Translation o Together, these processes are known as gene expression. o “The Central Dogma of molecular biology” All cells store their hereditary information in the same linear chemical code – the DNA o Phosphate, sugar, and a base combined to make a nucleotide. o A nucleotide is building block of DNA. o When nucleotides bond to each other, it creates a DNA strand. o Different nucleotides pair up and templates polymerization of new strand. o This forms double stranded DNA and into double helix structure. o
