A scientist has sequenced a gene from a multicellular eukaryotic organism. Brendan claims that by analyzing the gene sequence and applying
the genetic code, he can conclude the sequence of amino acids in the protein that forms after the gene is transcribed and translated

Which statement provides the strongest evidence against the validity of Brendan's claim?

A. Regulatory proteins may activate or deactivate a gene, often by very complex mechanisms.

B. During transcription, a strand of mRNA is synthesized from complementary base pairs, with the substitution of uracil (U) for thymine
(T)

C. During translation, anticodons on tRNA bind to codons on mRNA as part of the process that forms the polypeptide.

D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
