The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
According to Chargaff's rule, pyrimidine and purine occur in equal ration (1:1) in the DNA of all cells. Adenine (A) and Thymine (T) occur in equal proportion while Guanine (G) and Cytosine (C) occurs in equal proportion in the DNA of an organism. This pattern is repetitive and found in both DNA strands.
