Detailed explanation-1: -Adenine pairs with thymine and cytosine pairs with guanine. If cytosine = 14% then guanine = 14%. So, A= 36%, T= 36%, G = 14%.
Detailed explanation-2: -Since we know that 35% of the bases in the section of DNA are adenine, we can conclude that 35% of the bases are thymine. This is because adenine will always pair with thymine, so there will be just as many thymine bases as adenine bases. Together, adenine and thymine compose 70% of the segment.
Detailed explanation-3: -Answer and Explanation: The DNA of an organism is studied and found to contain 14% guanine. This organism should have 36% thymine and 14% cytosine in its DNA. The proportion of guanine is the same as cytosine and that of thymine is the same as adenine due to complementary base pairing rules.
Detailed explanation-4: -In a DNA sample, the percentage of adenine is 40% and percentage of thymine is 60%. What is your inference? According to Chargaff’s rule, Concentration of adenine=concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.
Detailed explanation-5: -If T=15%, then C=[100−15(2)]/2=35%
