In the same way that Nitogenous Turing decoded Enigma, the encryption machine used by the German army in World War II, several scientists managed to decipher the genetic code. The solution to this framework has allowed us to understand how cells work and make genetic manipulation possible. A code is a system of replacing fhe words in a message with other words or symbols, so that nobody can understand it unless they know the system. For example the genetic code. Although it seems to be a lie, all living beings except for some bacteria biologically work in the same way.

And it is that Jacques Monod already said, everything that is verified as true for E. From the cells of the blue whale, the largest animal on the planet, to the cells of a hummingbird, passing through humans, are the same. This is thanks to the genetic code, which allows the information of each gene to be transmitted to the proteinsthe executors of this information. This flow of information was named by Francis Crick, inas the central dogma of molecular biology Figure 1.

This is how genetic information is transmitted and expressed unidirectionally. However, later modifications were added. However, it has been seen that the replication of its RNA also occurs in viruses and that it can perform a reverse transcription to generate DNA again. The one we already know is the language of deoxyribonucleic acid DNAwound in a double chain and composed of hwat letters that correspond to the nitrogenous bases: adenine Athymine Tcytosine C and guanine G.

Another language very similar to the latter is that of RNA. It differs from DNA mainly in three aspects: i it is composed of a single chain instead of being double-stranded, dode its sugars are ribose instead basws deoxyribose hence the name of ribonucleic acid and iii it contains the base uracil U instead of T. The last language that remains for us to know is that of proteins, formed nitrkgenous 20 amino acids. The amino acids constitute each and every one of the proteins of any living organism.

The order of the amino acids that form the chain of the protein nigrogenous its function Figure 2. As we have been saying, the genetic code is the rules that follow the nucleotide sequence of a gene, through the RNA intermediary, to be translated into an amino acid sequence of a clde. The cells decode the RNA by reading its nucleotides in groups of three Figure 3. Since mRNA is a polymer of four different nucleotides, there are 64 possible combinations thd three bses 4 3.

This brings us to one of its characteristics: it is degenerate. This means that there are several triplets for the same amino acid synonymous codons. Figure 3. The genetic code with basees table of 20 amino acids Source: BioNinja The genetic code is not ambiguous since each triplet has its own meaning. All triplets make sense, either encode a particular amino acid baxes indicate read completion. Most amino acids are encoded by at least two codons. Methionine and tryptophan are the only amino acids that are codified only by a codon.

But each codon codes only for an amino acid or stop sign. The AUG codon serves as the start codon at which translation begins. These codons cause sequencr polypeptide to be released from the ribosome, where the translation occurs. The position of the start codon determines the point where translation of the is it possible to save a relationship after cheating and nitrogfnous reading frame will begin.

This last point is important because the same nucleotide sequence can encode completely different polypeptides depending on the frame in which it is read Figure 4. However, only one of the three reading patterns of a mRNA encodes the correct protein. The displacement in the reading frame causes the message no longer to make sense. As we said at the beginning, one of the main characteristics dnz the genetic code is that it is universal, since almost all living beings use it with the exception of some bacteria.

This is important because nitrpgenous genetic code shared by such diverse sqeuence provides important evidence what do the nitrogenous bases in the dna sequence code for a what do the nitrogenous bases in the dna sequence code for origin of life on Earth. The species of the Earth of today probably evolved from basse ancestral organism in which the genetic code what do the nitrogenous bases in the dna sequence code for already present.

Because it is essential for cellular function, it should tend to remain unchanged in the species through the generations. This type of evolutionary process can explain the remarkable similarity of the genetic code in present organisms. Although the human being itself continues to be an enigma for science, the revolution of the deciphering of the difference between ancient history and prehistory code has allowed us to delve into the functioning of our body, specifically that of our cells, and cross borders to genetic manipulation.

When DNA is isolated, cleaved with a specific enzyme, and hybridized under low-stringency conditions with a probe consisting hhe the core repeat, a complex ladder of DNA fragments is detected. In addition to their genomic DNA, many prokaryotes can contain watwhich are self-replicating extrachromosomal DNA structures that may, for example, confer resistance to a specific antibiotic.

This method replaced ABO blood antigen systems which cannot establish paternity but can conclusively exclude an alleged father from being a candidate. Vol 6 No 3 In conclusion, an exciting age is thd for research on how these G-quadruplex structures truly work. As dja above, G-quadruplexes are formed by rings of four guanines connected with hydrogen bonds in planar array, known as G-tetrads. The phosphate groups face the outside of the structure, while bases are located on the inside and result in pairs of facing bases guanine—cytosine and adenine—thymine connected by hydrogen bonds. More specifically, telomeric DNA consists of a repetition of guanine-rich nucleotides — usually TTAGGG for eukaryotic cells — between 9, and 15, nucleotides long.
