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 type of analysis is also used in the type of DNA testing that is used in crime labs or used to determine paternity. POINT MUTATIONS, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another.oint mutations that occur within the protein coding region of a gene may be classified into three kinds... A. nonsense mutations: code for a stop, which can truncate the protein. B. missense mutations: code for a different amino acid. C. silent mutations: code for the same amino acid.
