DNA, RNA, Protein Synthesis, & Mutation
In this biology worksheet, students identify and label the diagram shown by stating what each part of the diagram represents on the line. Then they use the DNA strand as the original strand and complete the data table. Students also...
Curated OER
Protein Synthesis Worksheet
Future geneticists use base pairing rules to build DNA and RNA polypeptide strands, and then explain both transcription and translation. Although the chains themselves are a little blurry, there is plenty of room in them for learners to...

Gas Transport
In this biology worksheet, students examine the transport of gases in the circulatory system and how they bond to hemoglobin.
Curated OER
Catalase and Catalysis
Students explore enzyme catalysis through a series of experiments. In this chemistry instructional activity, students determine the factors affecting catalysis. They explain the different uses of this process.

Structural Changes in a Protein
Students observe and manipulate the structure of a protein. They form an alpha helix, a beta sheet, and add disulfide bonds. They create a multimeric protein and compare their location with other students.
Curated OER
DNA and RNA Exercises
In this protein synthesis instructional activity, students answer 14 short answer questions about the process of making proteins from DNA.
Curated OER
Protein Synthesis
In this biology worksheet, students complete a crossword puzzle with 35 questions on protein synthesis. They identify the different parts of the cell involved in the process.
Curated OER
Proteins
Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...
