Question

DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One aspect of DNA that allows it to accurately store genetic information is the base pairing from Chargaff's first rule of the four nucleotide bases. If the A content of a DNA molecule is 22 % , what are the percentages of the remaining bases

Answer 1

Answer: thymine= 22%, guanine=28%, cytosine=28%

Explanation:

Chargaff base pair rules stated that DNA in an organism occurs only in ratio 1:1. Adenine, guanine, cytosine and thymine are the four types of bases  of DNA, DNA bases always occurs in pairs which are complementary to each other. adenine pairs with thymine while cytosine pairs with guanine as a result their chemical properties. therefore if adenine is 22%, thymine will also be 22% and if guanine is 28% then cytosine will also be  28% therefore, Bases altogether gives you 100%
