DNA Words Are Three Letters Long
DNA writes 64 different words but only codes for 20 different amino acids. Budding scientists learn about where each of these numbers come from and why they aren't equal with an online interactive. The resource explains the research, the...
Balanced Assessment
Genetic Codes
Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.
