Common configurations for a standard dump truck include the four wheeler. (4x2) which has one powered rear axle, the six wheeler (6x2 or 6x4) with one or two powered rear axles, the tri-axle with one lift axle and two powered axles, and the quad with two lift axles and two powered axles.
But not always: a silent mutation is a type of mutation in the coding region of a gene that doesn't actually change the amino acid sequence of the protein that is made. Below, learn how silent mutations work and why they're no big deal for an organism.
Example of a Silent Mutation. In this diagram, you can see an example of a silent mutation. First, look under 'No mutation.' As you see, the normal DNA sequence at this spot in the gene is TTC. This sequence would be transcribed to AAG in the messenger RNA. AAG directs the addition of the amino acid lysine into the growing protein.
