Explanation:
The Chargaff rule states the relationship in DNA molecules based on nucleotide composition. It is based on the fact that in a double-helical DNA molecule, a purine base of a strand always pairs with a pyrimidine base of the other strand. According to the Chargaff rule, the number of adenine bases equals the number of thymine bases, and the number of guanines equals the number of cytosines.
According to the given information, the percentage of adenine (A) in the DNA of a particular organism is 30%. This means that the DNA of this organism would have 30% of thymine nucleotides. Out of total 100% DNA nucleotides, the proportion of guanine + cytosine nucleotides= 100- (30 + 30) = 100-60= 40.
In a double-helical DNA, the number of guanines equals the number of cytosines. Therefore, the percentage of guanine and cytosine nucleotides each= 40/2=20%
<span>An easy way to calculate this function without using the SUM function itself is to simply place the two cell names together, separated by the plus sign. In this case, the syntax would simply read "=B7+E7", with dollar signs entered in as needed if the cell references need to be made absolute.</span>
