Item 4 The sequence of a complete eukaryotic gene encoding t

Item 4. The sequence of a complete eukaryotic gene encoding the small polypeptide, Met Tyr Arg Gly Ala is shown here. All of the written sequences on the template strand are transcribed into RNA. 5 CCCCTATGCCCCCCTGGGGGAGGAT 3 CAAAACACTTACCTGTACATGGG GGGGATACGGGGGGACCCCCTCCTAGIT TTGTGAATGGA CATGTACCC 5

Solution

Since the peptide sequence is met tyr arg gly ala, So the possible sequence of mRNA for the given peptide can be:
5\' AUG UAU/UAC CGU/CGC/CGA/CGG GGU/GGC/GGA/GGG 3\'

The complementary sequences of given DNA is as follows:
3\'GGGGAUACGGGGGGACCCCCTCCUAGUUUUGUGAAUGGACAUGUACCC5\'
5\' CCCCUAUGCCCCCCUGGGGGAGGAUCAAAACACUUACCUGUACAUGGG 3\'
So, the possible sequence of the mRNA for the given peptide is
5\'AUGUACCGCGGGAAAAAAAAAA3\'
