I have noticed that, in recent years, there have been a lot of violent, often mass, murders where the perpetrator was young, sometimes still a teenager, and the people around him/her, including family, said that they had not noticed anything concerning in his/her behavior before the murders.…
Ancient DNA reveals that canine and human genomes evolved in tandem, unlike the feline genome, which remained largely unchanged for thousands of years after the cats entered human’s life
The bond between dogs and humans is ancient and enduring.…
This post is a re-publication of the following article from the online journal The Conversation:
What is the ACE2 receptor, how is it connected to coronavirus and why might it be key to treating COVID-19?…

Cancer can be described as a disease of altered gene expression. In cancer cells, gene mutations modify the control of the cell cycle and cells don’t stop growing as they normally would.…
Cancer and gene regulation Read More »
Cancer is a collective name for many different diseases caused by a common mechanism: uncontrolled cell division. In cancer cells, mutations modify the control of the cell cycle and cells don’t stop growing as they normally would.…

The central dogma of molecular biology says that the DNA code is transcribed to messenger RNA, or mRNA, which, in turn, is translated to proteins.…
The study of nucleic acids began with the discovery of DNA, progressed to the study of genes and small fragments, and has now exploded to the field of genomics.…
No one knows exactly when viruses emerged or from where they came, since viruses do not leave historical footprints such as fossils.…

Each somatic cell in the body generally contains the same DNA. A few exceptions include red blood cells, which contain no DNA in their mature state, and some immune system cells, which rearrange their DNA while producing antibodies.…
The heterocatalytic function is how DNA controls the development of the body, that is how it decodes the genetic information and transforms it into specific proteins by transcription and translation.

The autocatalytic function is how DNA reproduces itself, that is the process of replication by semiconservative mechanism with duplication of genetic information.

The nucleic acids DNA and RNA are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.…
