Question

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 earth and life on mars have similars methods for storing and transmitting genetic information?

A: lipid
B: complex carbohydrate
C: protein
D: polynucleotide

Answer 1

B complex carbohydrate i think is the answer

Answer 2

Answer: Polynucleotide

Explanation: Polynucleotides are the chain of nucleotide monomers covalently bonded to each other. One such example is DNA which Deoxyribose nucleic acid and have a very distinct biological function. They store the genetic information and also transmit this information from one generation to another. Another example of polynucleotide is RNA which helps in the transcription of complex proteins.

All life uses polynucleotides as the basis for storing and transmitting the genetic information.
