Mutation: Causes a replacement of the usual amino acid to one that causes the protein folding.
Protein’s: primary structure is called sequence, made up of a series of connected amino acids just like beads on a string. - Gene mutations- How do gene mutations cause changes in the proteins that are produced?
The change in amino acid basically doesn’t alter the function of the resulting protein. - SILENT MUTATION
The change causes a stop codon to halt amino acid linkages. This leaves the protein short of subsequent amino acids, altering the 1, 2, 3 and quartinary structure of the protein. - STOP MUTATION
-Consider protein structure, it does not mean the protein is a fixed structure like a knife or happer, it can be more like a scissor or a rubber band as well, it can move in certain ways. - - Not all “mutations” cause structural changes in a protein. Only the very “mutations” implicated in the control of the function of the protein might cause the structure of the protein. - Studies revealed that every 8th position in the human genome varies from person to person, and many of these positional changes end up with different amino acids in their respective protein product. If such changes keep occurring among people for many many generations and each change causes structural changes and then functional changes, how do we explain that all the homologous proteins currently known have the same or at least very similar function AND structure among all the people around the world and sometimes shares the same function AND structure even with those from different organisms?
