Lesson Worksheet: Types of RNA Biology

In this worksheet, we will practice describing the components that make up RNA molecules and differentiating between tRNA, mRNA, and rRNA.

Q1:

Which of the following is not a base found in RNA?

  • AThymine
  • BUracil
  • CCytosine
  • DAdenine

Q2:

Which of the following correctly describes the structure of an RNA molecule?

  • AAn RNA molecule is formed of a single strand of nucleotides joined by a sugar–phosphate backbone.
  • BAn RNA molecule is formed of two strands of amino acids joined by hydrogen bonds that form between the amino groups.
  • CAn RNA molecule is formed of a single strand of amino acids joined by peptide bonds.
  • DAn RNA molecule is formed of two strands of nucleotides joined by hydrogen bonds that form between complementary base pairs.
  • EAn RNA molecule is formed when two DNA molecules interact and join together to form a more complex structure.

Q3:
