Answer #1

•From the given information,we can conclude that the nucleic acid is a Single stranded DNA.

•Since Thymine is present in the given nucleic acid, it can't be an RNA.

•In a double stranded DNA, due to basepairing, A=T and G=C i.e., the percentage of Adenine and Thymine would be same,and also the percentage of Cytosine and Guanine would be same.

•In the given information,the percentages vary and hence it can't be double stranded DNA.

•Therefore, it can be concluded that the nucleic acid of the given bacteriophage is single stranded DNA.
