Worksheet #1
16. Species
17. Kingdom
18. Order
19. Species
20. Kingdom, Phylum, Class, Order
21. Mountain Lions and Domestic dogs. They are most related because they
have more taxa in common.
22. Kingdom, Phylum
23. Class Amphibia
24. Primates (order), Hominidea (family), Homo (genus)
25. Rana temporaria is most related to green frogs (Rana clamitans). I know
this because they share the same Genus, which means they also share the
same family, order, class, phylum, and kingdom.

The replication cycle above illustrates a
lytic/lysogenic replication cycle.
Worksheet 2
3. Place these steps in order from 1-6 (1=first step, 6=last step)
The host cell lyses (bursts open!) and releases 100-200 new virus particles ___
Virus injects DNA into host cell ___
Virus attaches to the host cell ___
The newly released viruses can continue the cycle of infecting new cells ___
The viral DNA takes over the cell’s machinery and directs the production of viral
parts ___
The viral components (or pieces) are assembled into new virus particles ___

organisms are classified today?
Worksheet 3
Statement
a. Viral Genes are expressed immediately after the virus
infects the host cell.
b. Many new viruses are assembled.
c. This cycle involves a virus entering the host cell.
d. Viral DNA is integrated into the host cell’s chromosome.
e. Viruses are released from the host cell by lysis or
Exocytosis.
f. Reverse transcriptase is used to make DNA from RNA of a
