One “ Start ” codon (AUG) marks the beginning of a protein. AUG encodes the amino acid, called Methionine. Three “ Stop ” codons mark the end of a protein and terminate the translation. WebDNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and … how much is the upright walker
