The possible codons for Leucine in DNA are as follows: AAT, AAC, GAA, GAG GAT, GAC. Based on this, we see that they are the same in the second position (always A), and different in the first and third positions. This is called redundancy, where multiple nucleotide combinations code for the same amino acid.

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? Weba) There are three different in each codon, and each of these nucleotides can have one of four different bases. 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. WebMay 7, 2024 · There are 20 common amino acids in proteins. With four bases forming three-base codons, there are 64 possible codons. 61 codons are more than enough to code for the 20 amino acids, thus more than one codon codes for a single amino acid.
