Nuevo mecanismo de reparación de roturas del ADN

Chromosomal breaks are the most harmful damage for cells. If they are not repaired, they block the duplication and segregation of chromosomes, stop the growth cycle and cause cell death. These breaks appear frequently in tumour cells and are produced spontaneously during the replication of genetic material. To be ableRead More →

dna junk non-coding

In 1972,  the geneticist Susumu Ohno formalized the term “junk DNA” to describe DNA that do not encode protein sequences or non-coding DNA. In 2000, scientists presented the Human Genome Project confirming that around 98% of the human genome had no apparent function. Therefore, only about 2 percent of DNARead More →
