Theories of evolution throughout history
Throughout history, different theories have been postulated that tried to explain the diversity that exists between species. Let's take a tour of them. Fixism and Creationism At the beginning of the 19th century, the diversity that exists between species was justified as creations of God that remained immutable over time. This […]
Trisomies
The genome is the set of genetic instructions that are found in a cell and give rise to biological life. In the case of humans, these instructions are stored in 23 pairs of chromosomes (23 maternal chromosomes and 23 paternal chromosomes), with chromosome 23 being different depending on the gender of the individual (XX in […]
Different types of twins
When you have a double pregnancy, two situations can occur: That a double ovulation has occurred during the cycle, and two sperm fertilize those two ovules. This will give rise to dizygotic or fraternal twins. That there is only one fertilized egg, but that it divides into two in the first weeks of gestation, giving rise to […]
Golden rice: vitamin A food
Importance of vitamin A Vitamins belong to a group of foods known as micronutrients. Although the prefix "micro" means small, it has nothing to do with its importance, but with the amount that our body needs of these nutrients. Despite speaking of low amounts required, vitamin deficiency can have serious […]
The metabolism of vitamin D
It is very likely that you have heard that vitamin D is the sunshine vitamin. From ADNTRO we want to reveal to you that it is a half-truth. It is a teamwork between our diet, our body and sunlight. First of all, we must know that there are different forms of vitamin D: Both of them are [...]
Guidelines in my recommended diet according to my genetics
There are several genes involved in metabolic pathways that influence the care of our line: the type of metabolism (thermogenesis), appetite (satiety) and the breakdown of triglycerides (lipolysis). Depending on the genetic variants that you present for each of these factors, it is suggested that you follow some guidelines or others in your diet. And this [...]
Advances in the molecular understanding of aggressive breast cancer
Breast cancer represents the most important neoplasm in women, representing up to 15% of global cancer deaths [Globocan, 2020] Figure 1. Molecular studies have made it possible to advance in the understanding of how the development of this neoplasia works and the contribution of genetic mutations in aggressiveness, severity and progression […]
What is the human genome?
The human genome is our genetic information taken as a whole. It comprises the 3.2 billion "little letters" that make up our DNA, from the 22,000 genes we have in our body to the mitochondrial DNA, passing through the regulatory regions of the expression of these genes to proteins, the effector biomolecules of our organism. The DNA [...]
The types of RNA
Both RNA and DNA are part of the group of nucleic acids. Nucleic acids are polymers (substances made up of large molecules) formed by the union of subunits called nucleotides (the "little letters" that make up DNA or RNA). The main difference between DNA and RNA is their chemical composition. The […]
The arrival of genomic medicine thanks to mass sequencing (NGS)
Currently, the technology known as Next Generation Sequencing, or NGS for its acronym in English, Next Generation Sequencing, is considered the most advanced tool for the study and diagnosis of human genetic diseases. It should be remembered that since the development of the human genome project (Figure 1), in 2001,2 the cost of […]
