Answer;

-Nucleic acids;

Explanation;

-Living organisms all have DNA (deoxyribonucleic acid) and RNA (ribonuclei acid) which are both nuclei acids. All living organisms store genetic information using the same molecules, these are DNA and RNA.

-DNA and RNA both carry genetic information, however they differ in that RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose, and also RNA has the nucleotide base uracil while DNA contains thymine.

They are both helix it is just that DNA has two and RNA has one
