The purpose of this assignment is to familiarize you with some of the basic principles of enzyme
kinetics. The software you will be accessing (Biology Labs Online) will allow you to manipulate
various components of the system (temperature,
Lec 37 Notes
Biotechnology or genetic engineering genetically modifies an organism. The foreign or altered
DNA is called a transgene.
Uses of Biotechnology:
Tools to study fundamental developmental processes.
Example: The gene encoding green fluorescen
Lecture 34 Notes
I. Chemical signaling in plants
A. Cells sense a stimulus and produce a hormone
B. Hormone travels to responder cells, altering their behavior in a way that allows the plant to
respond to the stimulus in a advantageous manner.
Lecture 35 Notes
I. Bacteria and Archaea
A. Probably tens of millions of species on this planet (wherever you find water, youll find
microbial life, even in extreme environments)
B. More prokaryotic cells associated with a human than eukaryotic cells
Lecture 36 Notes
I. Basic outline of our nervous system:
A. Sensory receptors gather information from the environment and they transmit the
information to sensory neurons. (Frequently the sensory cells themselves are also sensory
neurons.) In these cells,
Lecture 29 notes
Introduction to developmental biology.
How does a multicellular animal develop from a single cell (fertilized egg)?
I. There are some fundamental developmental processes that are common to all animals,
Lecture 33 Notes
I. Hormones are small organic molecules that travel through the bloodstream from signaling
cells to remote target cells. They are present in very low concentrations but have profound
effects on the body.
Endocrine and neuroendocrine signa
Lecture 31 Notes
I. Introduction of anatomy (the study of an organisms physical structure) and physiology (the
study of how the physical structures in a organism work). The next two lectures will serve as an
introduction to these two broad fields within b
I. Many aspects of plant development are similar to animal development, with some important
A. Similarities: In plants, too, cells proliferate, signal to each other, and differentiate
into specialized cells. Apopto

Lecture 28 Notes
The cell cycle is regulated.
1. The length of the cell cycle varies in different tissues and different organisms.
2. Rapidly dividing cells (for examples dividing cells of a young embryo) have very brief or
no gap phases.
Lecture 27 Notes
I. Introduction to the cell cycle and mitosis
A. Purpose of the cell cycle and mitosis
1. To create two daughter cells that have the same genetic material as the mother cell
2. This requires replication of the mother cells DNA and an even
