Multiple Choice — Identify the choice that best completes the statement or answers the question. The process to go from mRNA to a protein is called __________.

• translation

• RNA

• transcription

• replication

Multiple Choice — Identify the choice that best completes the statement or answers the question. During DNA replication, which enzyme has the job of unzipping the double helix, by breaking the hydrogen bonds.

• ligase

• polymerase

• primase

• helicase

Multiple Choice — Identify the choice that best completes the statement or answers the question. Several differences between DNA and RNA allow the cell to differentiate between the two molecules, ensuring that transcription and translation occur appropriately. Which is one of the properties of RNA that differentiates it from DNA?

• RNA includes phosphate groups instead of nitrogenous groups.

• RNA contains uracil (U) instead of thymine (T).

• RNA is double stranded instead of single stranded.

• RNA contains cytosine (C) instead of guanine (G).

Multiple Choice — Identify the choice that best completes the statement or answers the question. Which organelle is DNA usually found in?

• chloroplast

• nucleus

• cell membrane

• vacuole

Multiple Choice — Identify the choice that best completes the statement or answers the question. What is the purpose of anti-codons (tRNA)?

• to ensure the correct amino acid is transfered to mRNA

• to make a copy of DNA

• to match the strand of DNA

• to decode a sequence of 4 nucleotides into an amino acid

Multiple Choice — Identify the choice that best completes the statement or answers the question. How many nucleotides are found in a codon

• 2

• 3

• 4

• 1

A DNA nucleotide may be made up of a phosphate group and
