What type of protein will support growth and normal maintenance?

A food that has all the essential amino acids an individual needs is called a complete protein. Complete proteins support growth and normal maintenance of body tissues. All animal proteins are complete proteins: i.e. milk, eggs, cheese, fish and meat have all nine amino acids.

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
