A 200 amino acid protein is encoded by a mature mRNA that is 800 bp long. Examination of this mRNA sequence and ORF analysis should reveal: a. Two major ORFs adding up to 600 bp b. One major ORF 600 bp long c. Many small ORFs corresponding to the exons d. At least 4 ORFs adding up to 600 bp e. One very large ORF nearly 800 bp long

You have isolated a protein that you think is encoded within a small region of DNA. In this region, there are 3 open reading frames (ORFs). Open reading frames are DNA sequences that are likely genes (have typical promoters, start and stop codons). ORF #1 has an open reading frame of 1500 nucleotides (AUG to stop codon). ORF #2 has an open reading frame of 600 nucleotides. ORF #3 has an open reading frame of 900 nucleotides. The protein you isolated is 33 kDa in size. If the average amino acid mass is 110 Da, then which of the above 3 ORFs most likely codes for this protein? a) ORF #1 b) ORF #2 c) ORF #3 d) None of the ORFs are large enough to encode this protein
