Question
Chapter 19, Problem 19.4PS
Summary Introduction
To determine: The original amino acid if in a gene there are three missense mutations affecting the same gene. The first mutations result in the substitution of arginine (Arg), the second results in the substitution of tyrosine (Tyr) and third results in the substitution of glutamine (Gln).
Introduction: Missense mutation is the type of mutation that is caused due substitution of one amino acid with the other. A change of a single
