a) 4
b) 6
c) 8
d) 12

The enzyme that creates mRNA (messenger RNA) from a DNA sequence is called:
a) Helicase
b) RNA Polymerase
c) DNA Polymerase
d) Ligase

Each codon of mRNA (hence each triplet in DNA) codes for one:
a) Carbohydrate
b) Lipid
c) Nucleic Acid

The specific amino acid carried by a tRNA (translating RNA) is determined by it's
a) Anticodon
b) Nucleotide
c) Nucleus
d) Codon

True of False? When amino acids are brought in by tRNA, they are joined together by hydrolysis reactions to form the growing protein.
a) True
b) False
c) a
d) b

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.
