How can twenty amino acids form proteins?

Answer 1

Yes. Twenty standard amino acids are used by cells in protein biosynthesis, and these are specified by the general genetic code.

Answer 2

There's theoretically an infinite amount. Not only does the sequence and length of the amino acid change the resulting polypeptide, but also how the amino acid chain folds into its secondary, tertiary, and sometimes quaternary structure. The folding of proteins can be extremely complex.

Answer 3

Amino acids are the building blocks of proteins. When amino acids are linked together in a specific sequence through peptide bonds, they form linear chains called polypeptides. These polypeptide chains fold into complex three-dimensional structures, ultimately forming proteins with diverse functions.

Answer 4

Yes, but there are 20 naturally occurring amino acids.

Answer 5

By Translation. ;)

Answer 6

A huge number of different proteins.
