6. Predict how a single change in the DNA nucleotide sequence could alter the formation of a protein - what are the possible outcomes?

(For example: what if the DNA should be AAA, but was "read" as ATA instead, what would
happen to the mRNA, the tRNA, and the amino acid)

American scientist, linus pauling, was one of many scientists racing to discover the molecular structure of dna. pauling initially thought that the molecule was a triple helix. later, james watson and francis crick unveiled their double helix model, which turned out to be an accurate description of the molecule's shape. why did watson and crick succeed when pauling failed?
