According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
It is the recycling process by which the rocks are formed, broken down and reformed.
Answer:
Sample A: 21.3%A, 28.7% G and 28.7% C
Sample B: 27.7% A, 22.3% G and 22.3% C
Explanation:
According to Chargaff's rules of base pairing, the amount of adenine in a DNA molecule equals the amount of thymine, and the amount of G=C.
<u>Sample A</u>
Contains 21.3% T, so it also contains 21.3% A. Therefore A+T= 42.6%
100% - (A+T) = (G+C)
100% - 42.6% = 57.4%
G+C add up to 57.4% of the DNA in sample A. And because G=C, there's 28.7% G and 28.7% C.
<u>Sample B</u>
Contains 27.7% T, so it also contains 27.7% A. Therefore A+T= 55.4%
100% - 55.4% = 44.6%
G+C add up to 44.6% of the DNA in sample B.
And G=C, so there's 22.3% G and 22.3% C.
