This seems to be an examination question. We should only give you some hints.
1. Compare the 5'-most cDNA sequence with genomic sequence, you will locate the transcription start site. You have to assume the cDNA sequence is a full-length one.
2. The first ATG in the cDNA sequence is usually the start codon. Then go down the triplet codons until you find one of the three STOP codons. If you have access to a DNA analysis program, it will translate it for you. Compare the translated sequence with the gvien protein sequence to confirm the predicted START and STOP codons.
3. Any sequences on the cDNA sequence that do not encode for protein are UTR.
4. Use the search function of the DNA analysis program (or word processing progress) to locate the primer sequences.
