List three characteristics of all living organisms.
A.
B.
C.
A. All living organisms are highly organized.
B. All living things have the ability to grow and develop
C. All living things can reproduce.
Prokaryotic/Eukaryotic two differences for each.
Prokaryotic:
1. Usually smaller in size 1.0-10μm
2. Has no nucleus and replicates DNA in free-floating environment.
Eukaryotic:
1. Has true nucleus and has membrane-bound organelles.
2. Has multiple of organized origin of DNA replication

The yeast Cdc2 gene from yeast is functionally homologous to the human Cdc2 gene. What does the term “functional homology” mean?
Functional homology at which structures relating to common ancestry is able to replace and work with a similar gene, but just expressed differently.
