Complete the following DNA strand, and indicate how many bonds are
formed for each complementary pair:3' GGTCATCG 5'5' CC AGC 3' --
Verified--Solution----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.
3' GGUCAUCG 5'
5' CCAGUAGC 3'
There are 2 bonds formed between A and U, and 3 bonds between G and
C.
How many amino acids are classified as being essential amino acids? --
Verified--Solution----9
True or False: The smallest biological unit of life is the molecule. --
Verified--Solution----False
, 2|Page
True or False: The genetic material within a prokaryotic cell is contained
within a membrane-enclosed region. -- Verified--Solution----False
What are the four main types of macromolecules found in cells? --
Verified--Solution----Proteins, Lipids, Nucleic acids and
Polysaccharides (Carbohydrates)
True or False: A virus is considered a microorganism -- Verified--
Solution----False
Describe the 4 basic bacterial morphologies. -- Verified--Solution----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
True or False: Archaea, a eukaryotic class of microorganisms, is noted
for its ability to survive under harsh conditions -- Verified--Solution----
False. They are prokaryotic.
Where can the two major types of nucleic acids be found in the cell and
what are their roles? -- Verified--Solution----While both DNA and RNA
can be found in the nucleus (center of the cell), only RNA is
capable of leaving the nucleus. DNA contains a vast amount of
hereditary information
