Polysaccharides are complex sugars or carbohydrates.
There are two types of polysaccharides in plants: cellulose and starch.
Polysaccharides generally perform two functions: energy storage and structural support.
Polysaccharides, also called glycan, are the form in which most natural carbohydrates occur. Polysaccharides may have a molecular structure that is either branched or linear.
Types Of Polysaccharides
Cellulose: The cell wall of the plants is made up of cellulose.
Starch: It is formed by the condensation of amylose and amylopectin.
Glycogen: It is made up of a large chain of molecules.
Inulin: It is made up of a number of fructofuranose molecules linked together in chains.

The right answer is 5.
To answer this question, we must think in the same way as the demonstration showing that codons of 3 are necessary to encode an amino acid (in terrestrial species).
To calculate the number of nucleotides in a codon in these new species: we should use the law of:
nucleotides existing ^ (number of nucleotides in a codon) = number of codons. (in order to have the number of possible codon combinations)
The number of codons must be greater than or equal to the number of amino acids (17).
2 ^ 1 = 2 (<17)
2 ^ 2 = 4 (<17)
2 ^ 3 = 8 (<17)
2 ^ 4 = 16 (<17)
2 ^ 5 = 32 (> 17)
32> 17 so the number of nulceotides in a codon must be 5.
The minimum size of a codon for the hypothetical Martian life-forms, which use only two bases (A and T) and have only 17 amino acids in their proteins, should be five bases. This size is needed to generate a minimum of 17 different codons.
The question is asking for the minimum size of a codon in these hypothetical Martian life-forms that use only two bases (A and T) in their DNA and have only 17 amino acids in their proteins. To analyze this, we must comprehend how codons function. A codon is a sequence of nucleotides in RNA that codes for a specific amino acid in a protein. In life on Earth, each codon is made up of three bases (each base can be A, T, C, or G), which makes for a total of 4^3 = 64 possible codons coding for 20 different amino acids.
However, in the Martian organisms, there are only two available bases (A and T) for constructing codons. In order to generate at least 17 different codons to code for the 17 different Martian amino acids, each Martian codon would have to be made up of at least 5 bases (since 2^4 = 16 is not enough, and 2^5 = 32 would be sufficient).
