Students investigate the use of technology in order to identify different sequences of amino acids by using online web tools. They enhance problem solving skills with amino acid identification skills and strengthening comfort with using...

Students examine protein synthesis and how DNA is transcribed.   In this investigative instructional activity students play a role in the messenger RNA when it creates nucleotides. 

Young scholars compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of...

Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Explains the workings of the codon translation chart which provides the keys to the structure of amino acids. Includes a widget where one can input a nucleotide triplet combination and see which amino acid it represents. Includes RNA and...

A stop codon is a nucleotide triplet in messenger RNA that signals the end of a protein during the translation process. Read about how this works, the different types of stop codons, and how a mutation can sometimes occur.

This lesson will introduce codons, and describe how they are used in protein synthesis. It is 2 of 5 in the series titled "Codons."

This lesson will introduce codons, and describe how they are used in protein synthesis. It is 5 of 5 in the series titled "Codons."

A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.

[Free Registration/Login may be required to access all resource tools.] How do you go from four letters to 20 amino acids? You need a code. This module introduces the genetic code and how to read it, defines codon and reading frame, and...

Learn how genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Also learn about start codons, stop codons, and reading frame.

The genetic code is actually the three letter combination of bases that codes for an amino acid. This article describes the discovery of this code. Article includes animations, pictures, video, biographical information, and quiz...

Very good description of the process of translation with a good graphic to go along with it. Includes a chart classifying all of the RNA Codons.

For the section including translation, go to "the genetic code" chapter in the table of contents. This explanation includes diagrams and illustrations as well as a codon code table.

Learn about structure and roles of transfer RNAs and ribosomes including codons, anticodons, and wobble. Also find out about Aminoacyl-tRNA synthetases.

Investigate gene expression with this collection of resources that explains how DNA is expressed to make RNA, how genes are turned "on" and "off", and what must occur for transcription to happen. The webpage explores gene expression by...

[Free Registration/Login may be required to access all resource tools.] Online activity covers the structure and function of nucleic acids. Students will learn about nucleotides, the different types of nitrogenous bases, and the...

[Free Registration/Login may be required to access all resource tools.] Translation involves translating the language of nucleotides to the language of amino acids. During this activity, translation in protein synthesis is explored along...

Go through this "tour" on protein synthesis to learn about translation (3rd page). Good graphics and the codon lookup table help in understanding the information.

This hands-on activity is an assessment of the students understanding of peptide and disulfide bonds formed during protein synthesis, and the structure of an amino acid (R-group plus the common structure that all amino acids share)....

[Free Registration/Login Required] Synthesize a protein by dragging the amino acids to the corresponding codon on the mRNA segment. You will need a sign-in to access this interactive but it will be well worth your time!

A look at protein synthesis in words and pictures. This website discusses the processes of replication, transcription, and translation. Also covered is Beadle and Tatum research that explains that one gene codes for one polypeptide....

[Free Registration/Login may be required to access all resource tools.] Introduces the genetic code and how to read it.
