Author: Sandra Ferreiro

Bioinformatics Specialist and Head of the Scientific Area at ADNTRO. She holds a degree in Biotechnology from Francisco de Vitoria University, where she received two scholarships for outstanding academic performance. She worked on a research project on left-right asymmetry in Newcastle, winning the award for best poster at the Cardiovascular Research Center Trainees Meeting (2018). She completed a Master's degree in Computational Biology at the Polytechnic University of Madrid. There, she studied metabolic interaction networks in the microbiome of patients with Crohn's disease and ulcerative colitis at the CBGP research center, a Severo Ochoa Center of Excellence (2020). Since 2020, she has worked as a Bioinformatics Specialist at ADNTRO, where she develops predictive models, performs annotations and analyses of pathogenic variants, conducts GWAS literature research, and engages in science outreach.

What is meiosis?

Meiosis is a cell division process that occurs exclusively in sex (or germ) cells in sexually reproducing organisms. This process results in the formation of gametes (eggs and sperm). What is the importance of meiosis? Unlike mitosis, which produces cells identical to the parent cell, meiosis produces two or more identical cells.

What are the phases of the cell cycle?

The cells of our organism are in continuous change due to a series of cellular events. All these events are called the cell cycle. Phases of the cell cycle The cell cycle consists of two phases: the interphase phase and the mitotic phase. Interphase During interphase, the cell grows and [...]

Proteins and amino acids

Did you know that proteins are the functional building blocks of our bodies? They are composed of amino acids, which in turn are encoded by our DNA. Discover more about proteins and amino acids in this article! What are amino acids? Amino acids are organic molecules found in nature that are essential for […]

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 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 [...]

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 [...]
