A. DefinitionB. History of Cell Biology

INTRODUCTION

I. Cell Biology

a. Zacharias Janssen, 1595 first light microscope

c. Robert Hooke, 1665 coined “Cellulae”d. Anton VanLeeuwenhoek, 1672 “Homunculus” and “Animalcules”

b. Galileo, 1609 focusing device

e. Charles Spencer, 1850’s first compound scopef. Max Knot & Ernst Ruska, 1933 first electron microscope

2. Basics of Cell Theory

a. Robert Dutrochet, 1824 plants made of cells

c. Theodor Schwann & Matthias Schleiden, 1839 Cell Theory

i. The cell is the basic unit in living organisms.

b. Robert Brown, 1824 Brownian motion & the nucleus

ii. The cell is the building block of organisms.

e. Rudolph Virchow, 1859 “Spontaneous Generation”

d. J. Purkinji, 1840’s coined the term protoplasm

iii. Cells arise from preexisting cells.

3. Cellular Control

a. Karl VanNageli, 1846 plant cells derived from direct division of maternal cells

d. Frank Meischer, 1871 proposed nuclein material of nucleic acids

b. E. Strausburger & Walter Fleming, 1840’s directions for growth and division of cells contained in the nucleusc. Gregor Mendel, 1860’s proposed a hereditary molecule was responsible for expression of traits in an organism

d. Robert Altmann, 1889 purified nucleic acids into purine and pyrimidine bases DNA in all cells, while RNA variablee. James Watson & Francis Crick, 1953 summarized research and built model of DNA

Characteristics

The parts == protein (capsid , landing gear, and injector) surrounding a nucleic acid core (genome = can be DNA or RNA)

Figure 18.4

2. Strategies

1. Lytic = inject, insert, take over, direct, and destroy

Figure 18.6

2. Lysogenic = same except hide for a time then lytic
