Interior of a human blood vessel. Something looks wrong, very wrong. Bacteria have entered the circulation, and the immunological system is reacting. All the alarms are on fire, while an army of white blood cells comes by, getting ready to […]

If there should be one rule that could apply to all fields of biological knowledge, it could be that they get more and more complex as we deepen into their study. Regarding genetics, the landscape has become not only more […]

Almost every one of our body cells bears in its nucleus about 2 meters of DNA containing the genes that shape our being. All that, roughly 20.000 protein-coding genes, regulatory and unknown-function sequences, tightly packed inside a structure that has […]

In multicellular organisms, embryonic stem cells develop into any of the different cell types that will form the adult, and along the development, they silence or activate different parts of the genome, giving rise to distinct cell identities, which are […]

I still remember the order and control exhibited by the chemistry of life that they explained to me in the early years of college. For me, the regulation of gene expression was the supreme paradigm of organization. The promoters, […]

A predicted collision between pair of black holes
The prediction late last year of a collision between a pair of supermassive black holes in a galaxy about 3.5 billion light-years from Earth has gotten support from a new study by […]

 
The term epigenetics refers to heritable changes in gene expression (active vs. inactive genes) that does not involve changes to the underlying DNA sequence. It results in change in phenotype without a change in genotype. An easily comprehensible example […]
