Topic: Protein Synthesis Worksheet
Summary: Students will practice DNA and RNA base pairing to build a polypeptide.
Students will also answer questions about transcription and translation and the central
dogma of molecular biology.
Goals & Objectives: Students will be able to apply base pairing rules for DNA and
RNA. Students will be able to explain the basics of transcription and translation.
Standards: CA Biology 1d. Students know the central dogma of molecular biology
outlines the flow of information from transcription of ribonucleic acid (RNA) in the
nucleus to translation of proteins on ribosomes in the cytoplasm. 4b. Students know how
to apply the genetic coding rules to predict the sequence of amino acids from a sequence
of codons in RNA.
Time Length: 30 minutes
Prerequisite Knowledge: Students know the basics of transcription and translation.
Materials:
Textbook for reference
Handouts and pencils
Have the CODON TABLE as a separate sheet so students have easy
access.
Procedures:
1. Students work on the handout by themselves.
Accommodations: Students with an IEP can take the handout home if they need extra
time, and/or do only the first page of the two page assignment.
Evaluation:
Each numbered question is worth 1 point for a total of 24 points.
