Answer:

309 (+3 for stop codon)

Step-by-step explanation:

  • The Genetic code is a scheme of 3 nucleotide base pair codons that code for different amino acids.
  • Each amino acid has a codon of 3 base pairs. Therefore, to calculate the size of the mRNA, we use the formula:
  • Total base pairs = Amino acids * 3
  • B.P = 103* 3 = 309
  • The length of the mRNA that codes for 103 amino acids is 309 base pairs plus a 3 base pair stop codon that terminates translation.
