How many possible unique codons are there? b) If DNA had only two types of bases instead of four, how long would codons need to be to specify all 20 amino acids? Expert Answer WebJul 19, 2005 · For example, using B on sequences 250 and 500 codons long would result in the first sequence being seemingly different twice as much from the expected distribution as the second one. Moreover, the overestimation at 250 codons may amount to as much as a quarter of the dynamic range of B.

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? http://www.dnaftb.org/22/problem.html
