Answer:
No, the same protein would not be formed if a sequence of DNA was read backwards. The sequence of DNA determines the sequence of amino acids in a protein, and the specific order of those amino acids is critical for the proper functioning of the protein. If a DNA sequence is read backwards, the resulting sequence of amino acids would be different, and would likely result in a non-functional protein.
It's important to note that DNA is read in a specific direction, referred to as the "5' to 3' direction." The 5' end of a DNA molecule refers to the phosphate group on the 5' carbon of the sugar molecule, while the 3' end refers to the hydroxyl group on the 3' carbon. The DNA polymerase enzyme that builds new strands of DNA always adds nucleotides to the 3' end, so the reading direction is always 5' to 3'.
In other words, the direction of the DNA sequence is important for the formation of a functional protein. Reading the sequence backwards would result in a completely different sequence, and therefore a different protein.
