Lecture 1

Introduction

Aims

• To place bioinformatics in a wider context.

Objectives

After this lecture you will be able to:

• describe the general transfer of biological sequential information within the cell.
• discuss a range of experimental methods, the kinds of data that these generate, and examples of biological questions that these can help to address.

Supplementary Material

Some of the lecture slides are available on-line (1 per page, 4 per page).

Cold Spring Harbor Laboratory's DNA Learning Center has produced a series of short videos on the Central Dogma of Biology.
