Life forms on a newly discovered exo-planet (planet found outside of our solar system) are somewhat similar to those found on Ea
rth. Their proteins are made of 10 different amino acids and their DNA and RNA only contain two different nucleotide bases, instead of four. This observation suggests that the codons coding for the amino acids are likely to be at least how many bases long?
In the given question, the total number of amino acids is about 10 and the number of nucleotide bases is only two.
So these two nucleotides will be arranged in a maximum of as there are only two nucleotides and either each nucleotide will code for a single amino acid or in pairs of two it will code for specific amino acids. Therefore the maximum amino acid chain will be formed by the four bases of amino acids.
Explained by natural selection. Those with favored traits in an environment are more likely to survive and pass down the allele. Thus in this situation a grey rabbit is more likely to survive and blend in.
