Solution
The correct option is D Any one of the above
Both DNA and RNA have four bases, that includes two purines and two pyrimidines, in the nucleotide chains. There are two purines namely adenine and guanine and three pyrimidines namely cytosine, thymine and uracil. The purines adenine and guanine and the pyrimidine cytosine are common to both DNA and RNA. DNA has the pyrimidine thymine; RNA has the pyrimidine uracil. Transfer-RNA has 7-15% post-transcriptionally modified bases like dihydrouridine (D), ribothymidine (T) and pseudouridine. In the given sequence, "GAG,AGG,GGA,CCA" thymine or uracil or the abnormal bases are not shown. It shows only the bases which are common to DNA/mRNA/tRNA; thus, it can be a sequence of DNA/mRNA/tRNA.
