Meaning
1
Base pairs
/beɪs ˈpɛrz/
Two matching chemical units that connect the two strands of DNA together, like rungs on a ladder.
2
Sugar phosphate backbone
/ˈʃʊɡər ˈfɒsfeɪt ˈbækboʊn/
The repeating chain of sugar and phosphate molecules that forms the outer part of the DNA double helix and holds the genetic information in place.
3
Adenine
/ˈædɪniːn/
One of the four basic building blocks found in DNA that pairs with thymine to help store genetic information.
4
Thymine
/ˈθaɪmiːn/
One of the four basic building blocks found in DNA that pairs with adenine to help store genetic information.
5
Guanine
/ˈɡwɑːniːn/
One of the four basic building blocks found in DNA that pairs with cytosine to help form the genetic code in living things.
6
Cytosine
/saɪˈtəsiːn/
