A forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine?The number of adenine will be equal to the number of guanine.The number of adenine will be equal to the number of all the other bases.The number of adenine will be equal to the number of thymine.The number of adenine will be not equal to the number of any other base.

DNA molecule possess two chains that lap around each other forming double helix and transmit genetic information used for growth, development, working and replication of all living organisms including multiple viruses. In DNA there are four bases which include adenine, guanine, thymine and cytosine. The bases in DNA are connected by hydrogen bonding. Adenine pair with thymine by two hydrogen bonds and guanine pair with cytosine with three hydrogen bonds. Since adenine and thymine are pai, number of adenine bases will be equal to the number of thymine bases. Hence the forensic scientist can find the number of adenine if he has the number of bases of thymine. So the correct answer is the number of adenine will be equal to the number of thymine.
