Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
A peplomer is a glycoprotein spike on a viral capsid or viral envelope. These protrusions will only bind to certain receptors on the host cell; they are essential for both host specificity and viral infectivity.
They are formed by natural processes like anærobic decomposition. They contain energy from ancient photosynthesis. They can literally be around 650 million years old.
