What is DNA and RNA:

DNA and RNA are acronyms of chemicals involved in the transmission of hereditary characters and in the production of compound proteins, which are the main constituent of living beings; They are nucleic acids found in all human cells.

According to biology, DNA makes RNA, which makes protein (although there are exceptions like retro viruses, for example, the AIDS virus). The information contained in the DNA is recorded in the sequence of its bases in the chain, which indicates another sequence, that of amino acids that make up proteins. DNA is not the direct manufacturer of these proteins; for this it forms a specific type of RNA, the messenger RNA. The genetic code is in the DNA, in the nucleus of cells, while proteins are in the cellular cytoplasm, where the messenger RNA goes.

DNA

DNA is a molecule formed by two chains in the form of a double helix, which are made up of a sugar, a phosphate group and a nitrogenous base. The double helix is ​​an essential factor in DNA replication during cell division, where each helix serves as a template for a new one.

RNA

RNA stands for ribonucleic acid (RNA), which is a molecule also formed by a sugar, a phosphate group and a nitrogenous base. RNA is responsible for the synthesis of cell proteins, they are usually formed in single strands, which can sometimes be folded.

Difference between DNA and RNA

In the cell, DNA is found in the nucleus, and RNA is produced in the nucleus but migrates to the cytoplasm.

As for pentose (the structural monosaccharide that is present in the nucleotide), there is ribose in RNA and deoxyribose in DNA.

Another difference between DNA and RNA lies in their structures. As for the number of strands, RNA usually has a single helix, while DNA has a double helix.

Regarding the pairing of nitrogenous bases in both RNA and DNA, cytosine is similar to guanine. The difference is that in RNA adenine is similar to uracil and in DNA adenine is similar to thymine.

In structural terms, other differences between RNA and DNA are:

The pentose (sugar) present in RNA is ribose, while in DNA it is deoxyribose.

In RNA there is the uracil nitrogenous base, while in DNA there is thymine.
