The Genetic Code

Science, Grade 6


Table Of Contents: The Genetic Code

1. What Is the Genetic Code?
The correspondence between the RNA triplets or codons and specific amino acids that are used to form a particular protein is called the genetic code.
2. UUC Codes for Phenylalanine
For example, the triplet code UUC on a messenger RNA always pairs with the transfer RNA that carries the amino acid phenylalanine.
3. Genetic Code Table
This is the Genetic Code table. Find the codon UUC by starting with the left column, then going across the top, and then down the right column. UUC corresponds to the amino acid phenylalanine.
4. Universal Nature of the Genetic Code
The genetic code is the same in nearly all organisms.
