Suppose that part of an amino acid sequence of a protein changed from tyrosine-proline-glycine-alanine to tyrosine-histidine-glycine-alanine. This change was most likely caused by a point mutation called a <u>substitution</u>.
<u>Explanation:</u>
Any protein is synthesized by joining a number of amino acids together. This amino acid is placed based on the sequences of the DNA , for every 3 sequence there is an amino acid that is synthesized and therefore it is called as a triplet codon, since there may be many sequence for a single amino acid we call it as degenerate codon.
The nurses auscultated for heart sounds in the area of Erb point.
The fifth point of auscultation for the heart test, known as "Erb's point," which is occasionally given to the eminent German neurologist Wilhelm Heinrich Erb (1840–1921) without any supporting documentation, is positioned in the third intercostal gap near the sternum. At the third intercostal gap and the left lower sternal border is the auscultation location for heart sounds and heart murmurs known as Erb's point.
The spinal accessory nerve in the posterior nerve triangle is located at Erb's point (also known as the great auricular nerve) at the location where it enters the trapezius muscle. At the end of expiration, the third intercostal gap on the left (Erb's point) is often the ideal place to detect the murmur of aortic regurgitation because it is quiet, high-pitched, early diastolic and decrescendo.
