In one polynucleotide stand of a DNA molecule, the ratio of A+T/G+C is...
A+T/G+C is ratio which is different for different species , but constant for particular speciesA+G/T+C is constant for all double stranded DNA and its value is 1 .because for dsDNA A=T are always same in number similarly G&C are also same number .

In one polynucleotide stand of a DNA molecule, the ratio of A+T/G+C is...
Understanding the Problem:
We are given the ratio of A T/G C in one polynucleotide strand of a DNA molecule, and we need to determine the A G/T C ratio of the entire DNA molecule.
Given Information:
Ratio of A T/G C = 0.3
Solution:
To solve this problem, we need to understand the base pairing rules in DNA. In DNA, adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C). This means that the number of adenine bases should be equal to the number of thymine bases, and the number of guanine bases should be equal to the number of cytosine bases.
Let's assume that there are 100 bases in the polynucleotide strand of the DNA molecule. According to the given ratio, the number of adenine bases (A) would be 30 (0.3 * 100) and the number of thymine bases (T) would be 70 (100 - 30). Similarly, the number of guanine bases (G) would be 30 (0.3 * 100) and the number of cytosine bases (C) would be 70 (100 - 30).
Now, let's calculate the A G/T C ratio of the entire DNA molecule.
Calculating the A G/T C Ratio:
The A G/T C ratio is defined as the ratio of the total number of adenine and guanine bases (A G) to the total number of thymine and cytosine bases (T C).
Total number of adenine and guanine bases (A G) = 30 + 30 = 60
Total number of thymine and cytosine bases (T C) = 70 + 70 = 140
A G/T C ratio = (A G) / (T C) = 60 / 140 = 0.4286
Final Answer:
The A G/T C ratio of the entire DNA molecule is approximately 0.4286.
Therefore, the correct answer is 0.4.
(Note: None of the given options match the calculated value exactly, so it seems like there may be a typo in the options provided. However, based on the calculations, the closest option would be 0.4, which is not among the given options.)
