FUNTIONAL GENOMICS: GENOMES AT WORK After the groundbreaking gene-splicing experiment of Paul Berg in 1972, Molecular Biology exploded. Soon everybody was cloning genes, the biological barriers between all kind of biological barriers were broken with transgenic experiments, the amounts of DNA bases sequenced per day went past the 10,000 in less than five years, and the duplication of DNA in the lab was increased to never undreamed of speeds thanks to the technique of PCR. Soon scientists realized that working one gene at a time was an extremely slow work and the idea was came up: “let's sequenced the whole genome.” Thus was born The Human Genome Project (HGP)and a new science Genomics. Here we will talk about genomes at work.,After the groundbreaking gene-splicing experiment of Paul Berg in 1972, Molecular Biology exploded.

MOLECULAR AND CELULLAR MEDICINE ADVANCES = ETERNAL YOUTH? In my previous articles I have told you about the ways they think life will be extended in the near future. They deal with the replacement of cells, organs or disease-related genes. However, those are solutions to the consequences of accidents, diseases and aging. Now I want to tell you about a series of experimental results that strongly indicates that the fountain of youth lies in a set of genes that regulate how we age. Thus, life could be extended if and when the molecular doctors learn how to modulate the action of those genes. aging • genes • gene therapy • diseases • dna
