DNA replication, transcription and translation
To understand how our organism works, it is necessary to go to the base of everything, to how our DNA works. There are three fundamental DNA processes without which we would not exist: replication, transcription and translation. These processes belong to the central dogma of molecular biology, a fundamental concept that establishes the sequence of events that [...]
What is nutrigenetics and what is a nutritional DNA test used for?
Nutrition is a fundamental pillar for maintaining good health and overall wellness. Science proves it with each new study published. Thanks to this progress, in recent years it has become clear how important it is to have a good diet together with a healthy lifestyle to prevent diseases and [...]
What is DNA?
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries our genetic information for the development and functioning of an organism. It consists of more than 3 billion base pairs ("little letters") in each of the cells of our body. In this article we will see what DNA is, its functions and its structure. To [...]
Glossary - Main concepts of Genetics
In this article you will find genetic concepts that will help you to understand our genetic tests. What is DNA DNA (deoxyribonucleic acid) is the biological molecule that contains the genetic information of all living things. DNA is found mainly in the nucleus of cells. It is made up of a series of [...]
Physical similarities between strangers
Surely throughout your life you have come across a person who reminds you of a friend, family member or acquaintance. If you have found yourself in this situation and are wondering how this could be possible, you are in the right place. In this article we will talk about unknown twins: Are there people who, without [...]
Clinical recommendations in pharmacogenetics
Did you know that nowadays, there are many drugs for which a genetic study is recommended and even mandatory? In recent years, thanks to the development of genomic techniques for massive sequencing and analysis with new bioinformatics tools, many biomarkers have been identified that are associated with how [...]
What are aneuploidies?
The genome is the set of genetic instructions found in a cell that 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 the 23rd chromosome being different depending on the gender of the individual (XX [...]
What is genetic imputation?
Imputation in genetics refers to the statistical inference of unobserved genotypes (not extracted in the laboratory analysis). And you may ask, how is it possible to infer the genotype of a variant that has not been analyzed? How reliable is it? Linkage disequilibrium Linkage disequilibrium Genetic imputation is possible thanks to [...]
Alzheimer's
What is Alzheimer's disease? Dementia, also called major neurocognitive disorder, encompasses a set of concurrent symptoms whose main symptom is severe cognitive impairment that affects the functioning and activities of daily living of those who suffer from it. Alzheimer's disease is the most common form of [...]
What is Epigenetics?
The term epigenetics was coined in 1942 by Conrad Waddington, a British developmental biologist, to describe the effects of external influences, such as diet and environment (environmental factors), on the development of organisms. In recent decades, it has become clear that epigenetic information plays a much more important role [...]
