Reading the Dna Code: Making Protein
Students study DNA decoding and protein synthesis. They use the amino acid table to translate DNA, break DNA strands into three nucleotide codes, and translate nucleotides into amino acid protein codes. They research the importance of...
Cornell University
Extracting DNA
Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.
