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.
Which of the following is not a base found in RNA?
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.
RNA can be categorized into different types based on its role in the cell. Which type of RNA is formed after a section of coding DNA has undergone transcription?
Ribosomes are formed from ribosomal RNA and polypeptides. What role do ribosomes have in a cell?

The diagram provided shows the basic structure of an RNA nucleotide, which contains a pentose sugar. Which pentose sugar is found in an RNA nucleotide?
Which of the following diagrams best demonstrates the structure of an RNA molecule?
Which type of RNA does this diagram show the basic structure of?
True or False: After translation, the tRNAs remain attached to the polypeptide chain and are removed in the endoplasmic reticulum where the proteins undergo some modification.
