WebViewed 6k times 3 We need to consider six reading frames when considering the potential of DNA to encode protein (three frames for each strand). But only one strand is transcribed into RNA — the so-called coding strand. It would therefore seem to me that there are actually only three reading frames to consider. Why, then, do people refer to six? WebApr 28, 2024 · A tRNA can be classified based on the amino acid it carries, giving rise to 20 different tRNAs. Alternatively, they can also be grouped based on their anticodon. There are 64 possible codons arising from a combination of four nucleotides. Of these, 3 are stop codons that signal the end of translation.
