The most striking difference is, as the names suggest, the number of strands:

  • DNA forms a double-stranded helix, while RNA forms a single-stranded helix.

RNA is transcribed from DNA, meaning, if the body needs a certain kind of protein, DNA unwounds, unzipps, and is used as a template to assemble RNA, the single-stranded nucleic acid molecule. The process is called transcription.

RNA is than used by the ribosomes to put together the needed proteins through a prcess, called translation.

Other differences are:

  • Also, as the name suggest DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) differ in the number of Oxygen they contain.

Both nucleic acids are made up from a five carbon sugar, a phosphate group, and a nitrogenous base.

  • The nitrogenous base of DNA contains: Adenine, Guanine, - Thymine, and Cytosine

The nitrogenous base of RNA contains: the same, except it contains Uracil instead of Thymine.

The genetic material in viruses can be either double-stranded DNA or RNA.


Why is RNA shorter than DNA?

RNA is shorter than DNA because RNA is typically single-stranded, while DNA is double-stranded. This means that RNA molecules have a shorter length compared to the longer double-stranded DNA molecules.


Is DNA and RNA double-standard?

No, DNA is usually double-stranded, consisting of two strands that are complementary to each other. RNA, on the other hand, is usually single-stranded. There are exceptions to this, such as certain viral RNA genomes that can be double-stranded.


Is DNA or RNA triple stranded?

DNA can form triple-stranded structures, although this is not common in nature. RNA can also form triple-stranded structures, particularly in certain non-canonical forms of RNA. Overall, triple-stranded structures are less common than the more prevalent double-stranded forms of DNA and RNA.


Is it true that the genetic material in DNA or RNA is single-stranded?

No, the genetic material in DNA is double-stranded, while RNA can be single-stranded.
