12 Biology--THIS IS URGENT

In relation to a work sheet on translation and transcription: If you worked backward, starting with the amino acid sequence of the protein, would you obtain the same DNA nucleotide sequence? Why or why not? THANKS!!!

  1. I have been thinking...and I think this is possible, because it is easy to find the pairs, because working backwards is almost the same as working forwards. But, once you are done with the changing of the bases, to get the nucleotide sequence you would have to change all of the uracils to thymines. But, what happens if when going forward codons are removed, you wouldn't be able to work backwards then right? You wouldn't know that they were missing?

  2. but would it change because some of the codons are extracted during the introns excision ??
