RIBONUCLEIC ACID (RNA) - Nucleic acid composed of a single polynucleotide strand. RNA nucleotides contain ribose rings and uracil unlike deoxyribonucleic acid (DNA), which contains deoxyribose and thymine.

DNA (deoxyribonucleic acid)
The long carbon-chain molecule that records information to govern the biological activity of the organism. DNA carries the genetic data passed to offspring.

deoxyribonucleic acid (NASA Thesaurus) The molecule that encodes genetic informatiion - a double-stranded moleculeeld together by weak bonds betweeen base pairs of nucleotides. Used for DNA. departure (NASA SP-7, 1965) = deviation, sense 1.
all monomers having the same "handedness" (amino acids being left handed, and nucleic acid sugars being right handed). Homochirality is essential for the formation of functional ribozymes (and probably proteins too).
A virus consists of a single- or double-stranded nucleic acid and at least one protein surrounded by a protein shell, called a capsid; some viruses also have an outer envelope composed of fatty materials (lipids) and proteins.
Human beings are composed of different types of large molecules: proteins, nucleic acids, lipids, carbohydrates, etc. These molecules are held together by intermolecular forces. An example is the peptide bond that links amino acids together.

Also, the "worms" are extremely tiny: They are 10-20 times smaller than the smallest "micro-fossils" from Earth. Being only 5 nm (only 500 times larger than most atoms), they are probably too small to support any nucleic acids (DNA or RNA) - the ...
Carl Sagan followed up on this with his own experiments in the 1960s, introducing ultraviolet radiation to the mix and creating various sugars and nucleic acids too.
