Answer:

The possibility of Adenine=40% and Thymine=60% is only in single stranded DNA molecule. In the question, the DNA sample referred is a single stranded DNA. If guanine=10% as guanine will always pair with cytosine, i.e.cytosine is also 10% then adenine and thymine accounts 80% as adenine will always pair with thymine.

A molecule of DNA cannot contain 60% thymine because this amount will surpass 100% in consideration of its complementary base.

DNA:

DNA or deoxyribonucleic acid is a biological molecule that stores genetic information in living cells.

DNA is a double stranded molecule that consists of nucleotide bases as follows:

  • Adenine
  • Thymine
  • Guanine
  • Cytosine

According to Chargaff in his rule, the amount of adenine & thymine and guanine & cytosine in a DNA molecule is the same, which must equal 100% overall.

Therefore, if thymine is 60% in the DNA, adenine will also be 60%, which in total has already surpassed 100% without adding the other two bases.
