Hello, welcome to 6 Minute English.
I'm Neil and with me in the studio today is Harry.
Hello, we all have two biological parents.
But in the future, if someone from the UK tells you they have three parents,
it might be true.
That's right.
This is because the UK has become the first country to approve laws,
allowing the creation of babies with DNA from three people.
DNA is the chemical structure present in the centre of a cell which defines somebody's characteristics.
This is to fight a particular disease.
Yes, some parts of the DNA, called genes, are faulty.
It means they don't work properly and this might cause problems later on.
A new technique will allow some of these genes to be replaced by healthy ones from a third person.
This practice is controversial.
People argue about it.
They fear we're going to mess with nature and end up with a Frankenstein's monster.
Wow, that would be frightening.
Let's hope it doesn't happen.
