<h3>What is a token economy?</h3>

This is a method of positive conditioning in which a token of some sort is given as a prize to reinforce positive behavior, with the idea that these tokens may then be exchanged for even greater reinforcers once a certain level is reached.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding
slava [35]

Answer:

In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy . In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid).  For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).
