1

unicellular organism with relatively simple cell structure.

prokaryote

2

compartmentalized cell structure with components bounded by intracellular membranes

eukaryote

3

in 2 major groups and may be unicellular or multicellular

eukaryotes

4

2 distinct types of prokaryotes

bacteria
archaea

5

3 major groups-of of organisms from evolutionary perspective

bacteria
archaea
eukaryotes

6

major difference between prokaryotic and eukaryotic cells

eukaryotic cell has a nuclear envelope

7

which cell has a nuclear envelope

eukaryotic

8

what class of proteins do eukaryotes use to pack their DNA

histones and chromatin

9

protein found in eukaryotes that complexes with DNA to form chromosomes

Histones

10

consists of DNA and proteins found in the eukaryotic nucleus

chromatin

11

what do histones do

-regulate accessibility of DNA to enzymes that copy and read the DNA
- Enable DNA to fit into nucleus

12

do not possess histones, dna doesn't exist in ordered tightly packed arrangement found in eukaryotic cells

bacteria

13

why are viruses neither prokaryotic or eukaryotic

don't possess structure of a cell

14

3 fundamental events for a cell to reproduce

-gene info must be copied
-copies must be separated
- cell must divide

15

how do prokaryotes reproduce

binary fission
