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.
This image shows an example of missense mutation. One of the nucleotides (adenine) is replaced by another nucleotide (cytosine) in the DNA sequence. This results in an incorrect amino acid (proline) being incorporated into the protein sequence.In genetics, a missense mutation (a type of nonsynonymous substitution) is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid.ot all missense mutations lead to appreciable protein changes. An amino acid may be replaced by an amino acid of very similar chemical properties, in which case, the protein may still function normally; this is termed a neutral, quiet, silent or conservative mutation.
