What makes us human ? is it our thoughts ?
Our emotions ? our behavior ?
All of these things make us who we are , but at the center of it all lies the genome(基因组)-the
genes inside our bodies that determine every thing from our hair color to our intelligence . o But if we could change our genome , would we
still be human ?
Recently , a group of scientists from the united States and south korea worked together to suc . cessfully“edit” a human embryo and re move a genetic mutation that would have
led to heart disease , reported the guardian
This was achieved with the help of crispr a gene - editing tool that allows scientists to edit the genome by cutting , changing or adding to
parts of it
