Complete the following DNA strand, and indicate how many bonds are formed for
each complementary pair:
3' GGTCATCG 5'5' CC AGC 3'
5' CCAGTAGC 3'
There are two hydrogen bonds between thymine and adenine.There are three
hydrogen bonds between cytosine and guanine.
In the strand above, there are eight complementary pairs.
How many amino acids are classified as being essential amino acids?
9
False
True or False: The smallest biological unit of life is the molecule.
False
True or False: The genetic material within a prokaryotic cell is contained within a
membrane-enclosed region.
What are the four main types of macromolecules found in cells?

Describe the 4 basic bacterial morphologies.
1. Coccus: bacteria is round or spherical
2. Bacillus: bacteria is a rod shape
3. Vibrio: bacteria is a curved rod shape
4. Spirillum: bacteria is in a spiral or corkscrew shape
False. They are prokaryotic.
True or False: Archaea, a eukaryotic class of microorganisms, is noted for its
ability to survive under harsh conditions
DNA and RNA;
DNA houses hereditary information and determines the inherited traits of a living
organism.
RNA is the hereditary information of some microbes, like some viruses. In
organisms wherein DNA is the hereditary material, the function of RNA is to
interpret the hereditary information found in DNA and ue that information to
help produce proteins.
Where can the two major types of nucleic acids be found in the cell and what are
their roles?
There are two major types of nucleic acids: DNA (deoxyribonucleic acid) and RNA
(ribonucleic acid). Nucleic acids are chemical molecules that carry genetic
information within the cell. DNA contains a vast amount of hereditary information
and is responsible for the inheritable characteristics of living organisms. RNA is
responsible for deciphering the hereditary information in DNA and using it to
synthesize proteins.
What are the two major types of nucleic acids and their roles?
2, 4
The plasma membrane (select all that are true):
1. Only restricts movement of materials into the cell
2. Is often a bilayer comprised of lipids
