Dear student
We welcome you to the exciting world of biology! Module BLG1501 deals with the basic
concepts of biology that are necessary for understanding how life begins. It is an honour
for us to introduce you to this stimulating and dynamic field. This module deals with the
theory component of biology. You should also simultaneously be registered for the
practical module, BLG1603. We hope that you will find this module interesting and
stimulating. To ensure that you master this field of study we urge you to read this orienta-
tion section in detail. You should use this study guide in conjunction with the tutorial letters
