Acute diseases are sudden, severe, and short term only. They quickly appear and worsen without warning and they disappear. Examples of this are flu or colds.
Chronic diseases, on the other hand, are long-developing diseases. The symptoms have been present for long time and it worsens as time progresses. Examples of this are Osteoporosis and heart disease.
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.
