A gene that does not contain introns has an Eco RI site just down stream of the translational termination codon in the 3' untranslated region. The size of the gene is 4 Kbp. The length of 3' UTR is 2 Kbp, the 5' UTR is 1 Kbp and that the open reading frame is 1kbp. Upon probing a southern blot of an Eco RI digested genomic DNA with the radioactively labelled fragment containing only the open reading frame, the size of the band detected by hybridization would be

A. 1 Kbp

B. > 2 Kbp

C. 0.5 Kbp

D. 1.5 Kbp
