Answer:

28% Thymine

Explanation:

DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%

Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.

Therefore; 22% C + 22% G = 44%

100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.

(b) Vaccination against the measles virus will not protect the child against the rubella virus. Why?
vekshin1
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.

The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.
