While analyzing the DNA of an organism a total number of 5386 nucleotides were found out of which the proportion of different bases were: Adenine 
, Guanine 
, Cytosine 
, Thymine 
. Considering the Chargaffs rule it can be concluded that:
Text Solution
Verified by Experts(i) The amount of adenine is always equal to the amount of thymine and the amount of guanine is always equal to the amount of cytosine; (ii) Adenine is joined to thymine with two hydrogen bonds and guanine is joined to cytosine by three hydrogen bonds; (iii) The ratio of adenine to thymine and that of guanine to cytosine is always equal to one, In the given organism, the DNA is not following the Chargaff
According to Chargaff's rules of base pairing,
(i) The amount of adenine is always equal to the amount of thymine and the amount of guanine is always equal to the amount of cytosine.
(ii) Adenine is joined to thymine with two hydrogen bonds and guanine is joined to cytosine by three hydrogen bonds.
(iii) The ratio of adenine to thymine and that of guanine to cytosine is always equal to one,
In the given organism, the DNA is not following the Chargaff's rule, hence it can be concluded that it is a single-stranded DNA, not double-stranded.
