Researchers compared the amino acid sequences of the transport protein in zebrafish, pufferfish, mice, and humans. They found many stretches with identical sequences in all four species. Does this mean that the corresponding mRNA base sequences are also the same in these four species? Explain why or why not.

No, the conforming mRNA base sequences are not similar to the four species since the redundancy within the genetic code infers the possibility for various codons to give comparable amino acids. Twenty amino acids exist in nature and the 4 bases (cytosine, uracil, guanine, and adenine) will have 64 codons.

Hence, an amino acid can have multiple genetic codes for its coding, making the process to seem redundant. Redundant genetic code creates the said difference in mRNA awaiting translation into the similar amino acids. The differences within the mRNA may encode same protein sequence.

Therefore, having analogous stretches of amino acids by similar organism does not match mRNA base sequence. For instance, the codons UCG, UCA, UCU, and UCC all code similar amino acid serine.
