Those strands are called the Sugar-Phosphate backbone. Connecting off the backbone are the bases. This creates a nucleotide which is what DNA is made up of. The nucleotides look like this...
Do the bases have names?
Yes and they go in pairs. They are called Adenine (A), Cytosine (C), Thymine (T), Guanine (G). A + T join together whilst C + G pair up. It looks like this...
Hydrogen bonds are holding these pairs together.
WOW! This is so interesting. Who discovered all of this?
Well DNA was sort of like a trophy. Everyone wanted it, but you had to win the race to get it. A scientist named Rosalind Franklin found the shape of DNA. She called it Photograph 51. But the photo got into the wrong hands of James Watson and Francis Crick and claimed it was theirs.
Woah, poor Rosalind.
She eventually got the credits for all her hard work. But this concludes your lesson on DNA. Your alarm is about to go off for you to wake up.
Thank you so much scientist, I can’t wait to tell Mum all about it!!
