3) If a DNA sequence consists of 12 nucleotides, how many mRNA (messenger RNA) condons (sets of three) will there be?
A
8
B
6
C
4
D
12
4) The enzyme that creates mRNA (messenger RNA) from a DNA sequence is called:
A
DNA Polymerase
B
RNA Polymerase
C
Ligase
D
Helicase
5) Each codon of mRNA (hence each triplet in DNA) codes for one:
A
Amino Acid
B
Lipid
C
Carbohydrate
D
Nucleic Acid
6) The specific amino acid carried by a tRNA (translating RNA) is determined by it's
A
Codon
B
Nucleotide
C
Anticodon
D

7) True of False? When amino acids are brought in by tRNA, they are joined together by hydrolysis reactions to form the growing protein.
A
False
B
True
C
b
D
a
8) True or False? Whenever a cell needs to, it can unzip DNA and make a transcript sequence so that a protein can be made. DNA then zips up.
A
b
B
True
C
a
D
False
9) True or False? The same amino acid can be carried by different tRNA's.
A
b
B
False
C
