There are many reasons why scientists think RNA came before DNA. RNA is found in viruses and some bacteria which were likely around before more complex organisms.
Deoxy-ribonucleic acid (DNA) and ribonucleic acid (RNA)
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
While RNA can exist in a double stranded form, DNA functions as genetic information storage. In addition, DNA contains thymine (T), whereas RNA contains uracil (U), so the answer is DNA.
Yes, more nucleic acids exist.

Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
RNA can move and DNA cant. DNA has a double helix strand and RNA is a single strand.
While RNA can exist in a double stranded form, DNA functions as genetic information storage. In addition, DNA contains thymine (T), whereas RNA contains uracil (U), so the answer is DNA.
There are several things. Some are circular DNA,RNA,enzymes,organic molecules etc
Yes, more nucleic acids exist.
An uracil base is in RNA but not in DNA
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
DNA and RNA. Viruses that use RNA often have to have enzymes that convert the RNA to DNA.
