Mahi Tuatahi 2 ^🔗

1. List the names of the four bases that make up the backbone of DNA
2. Which bases pair with each other?
3. What are the other components of that you found in your diagram? Take a look at sciPAD page 10 for hints.

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.
