Human pancreatic ribonuclease has 128 amino acid residues. What is the minimum number of nucleotide pairs required to code for this protein?
Added by Jeremy G.
Step 1
Each amino acid in a protein is coded by a sequence of three nucleotides, known as a codon. Therefore, to determine the number of nucleotide pairs required to code for a protein, we need to calculate the number of codons needed. Show more…

The Ribonuclease Gene Human pancreatic ribonuclease has 128 amino acid residues. (a) What is the minimum number of nucleotide pairs required to code for this protein? (b) The mRNA expressed in human pancreatic cells was copied with reverse transcriptase to create a "library" of human DNA. The sequence of the mRNA coding for human pancreatic ribonuclease was determined by sequencing the complementary DNA (cDNA) from this library that included an open reading frame for the protein. Use the nucleotide database at NCBI (www.ncbi.nlm.nih.gov/nucleotide) to find the published sequence of this mRNA. (Search for accession number D26129.) What is the length of this mRNA? (c) How can you account for the discrepancy between the size you calculated in (a) and the actual length of the mRNA?
The protein myoglobin is 153 amino acids long. What would be the minimum number of nucleotides required to encode myoglobin?
