The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

The radiation in space is not great for biological health. Space radiation is known to damage DNA. Many types of human cells have to frequently divide to replace cells that are worn out, old, or ...

Unlike "junk email" that is immediately deleted from the email box, "junk DNA" continues to exist in living creatures in nature such as bacteria, insects, and even mammals such as humans, alongside ...

Inaccuracy of DNA replication poses novel health risk The researchers conclude that – combined with the greater radition risk in space – the inaccuracy of DNA replication under microgravity could pose ...

Scientists at The Hospital for Sick Children (SickKids) have revealed a previously overlooked layer of genetic variation that could help explain why people experience disease differently, and why some ...

A new model offers a possible solution to the scientific question of why neutral sequences, sometimes referred to as 'junk DNA', are not eliminated from the genome of living creatures in nature and ...
