Protein Synthesis

DNA is one of the central molecules of life. It provides the blueprint for each of the proteins that cells assemble to perform all the tasks needed to support life. DNA, or its sister molecule RNA, is found in every living cell known to exist. This unit covers the molecular structure of each molecule, how DNA is replicated and synthesized, and the process of transcribing RNA and eventually assembling a protein molecule from that blueprint.


DNA Structure and Protein Synthesis Powerpoint Lecture

Download Microsoft Word Document

Purpose: This Powerpoint begins with the history of the discovery of the shape and structure of DNA molecule, including contributions from Rosalind Franklin, Watson, and Crick. That will transition into a section on how DNA is copied in the nucleus. Finally, students will learn the different steps of protein synthesis, including transcription in the nucleus and translation at a ribosome.

Essential Concepts: DNA replication, DNA synthesis, double helix, purines, pyrimidines, nitrogenous bases, adenine, thymine, guanine, cytosine, complementary strands, origins of replication, DNA polymerase, codons, triplets, transcription, mRNA, translation, tRNA, ribosomes, point mutations, missense, nonsense, frameshift mutations, insertions, deletions, mutagens.


DNA Structure and Protein Synthesis Lecture Notes Outline

Purpose: Taking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. This outline gives students a means to take notes that guides them toward important concepts and avoids the pitfalls of writing word-for-word or simply not taking notes at all. The outline is written as a series of questions, fill-in-the-blanks, or diagrams.

Essential Concepts: DNA replication, DNA synthesis, double helix, purines, pyrimidines, nitrogenous bases, adenine, thymine, guanine, cytosine, complementary strands, origins of replication, DNA polymerase, codons, triplets, transcription, mRNA, translation, tRNA, ribosomes, point mutations, missense, nonsense, frameshift mutations, insertions, deletions, mutagens.


Transcription and Translation Review Worksheet

View Worksheet
Transcription and translation review worksheet.

Purpose: This is a comprehensive review worksheet that covers the major aspects of protein synthesis. It starts with a diagram that students label, followed by a few simple questions about the process. Finally, they will take some snippets of DNA code to practice transcription and translation using the mRNA amino acid chart.

Essential Concepts: Protein synthesis, transcription, translation, DNA, mRNA, tRNA, ribosome, codon, anticodon, amino acid.

Purpose: This worksheet is a set of vocabulary words and practice questions meant to encourage students to condense their notes into a more manageable form to study from. The questions and vocabulary are taken directly from the lecture Powerpoint for this unit.

Essential Concepts: DNA replication, DNA synthesis, double helix, purines, pyrimidines, nitrogenous bases, adenine, thymine, guanine, cytosine, complementary strands, origins of replication, DNA polymerase, codons, triplets, transcription, mRNA, translation, tRNA, ribosomes, point mutations, missense, nonsense, frameshift mutations, insertions, deletions, mutagens.
