This type of mutation results in a shortened protein that may function improperly or not at all. An insertion changes the number of DNA bases in a gene by adding a piece of DNA. As a result, the protein made by the gene may not function properly. A deletion changes the number of DNA bases by removing a piece of DNA.
CPL is a revolution in antenna design offering a more powerful and efficient radiator over a wider band in a smaller footprint than before possible. A CPL antenna can be thought of as two antennas fabricated on a common substrate, generating orthogonal electric and magnetic wave patterns that together form a dense RF wave near the surface of the planar circuitry prior to propagation.
TBL is style of decrease. Some patterns use it because it causes the decrease to Slant in a specific direction---certain decrease styles are used to purposely slant to LEFT or Right--depending on pattern.
