Triplets
DNA is read by the cell in chunks of 3 pairs. Each group of 3 pairs
is called a triplet. Each triplet tells the cell to use
a certain amino acid.
Amino Acids
Amino acids are the molecules used to build all living things. There
are 21 of them and triplets tell the cell which ones to join
together.
![]()
Proteins
We are made up of proteins, which are in turn made of long chains of
amino acids.
