Suppose an alien form of life is discovered on mars. which of the following macromolecules would have to be discovered in this creature before scientists could suggest that life on earth and life on mars have similar methods for storing and transmitting genetic information?

a. lipid
b. complex carbohydrate
c. protein
d. polynucleotide

Answer;

D. polynucleotide

Explanation;

-Ploynucleotide is the macromolecule that would have to be discovered in this creature before scientists could suggest that life on Earth and life on Mars have similar methods for storing and transmitting genetic information.

-Polynucleotides are made from nucleotides that are linked via phosphodiester bond (phosphoric acid residue). They are formed by ribonucleotides are called ribonucleic acid (RNA); deoxyribonucleotides form deoxyribonucleic acid (DNA).

-DNA contains the genetic instructions for the development and function of living things. RNAs carry information of amino acid sequence from the genes to where proteins are assembled on ribosomes in the cytoplasm.
