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

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
b
B
True
C
a
D
False
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.
