What is the meaning of 5′ and 3′ carbon in DNA?

2 Answers 2. The 5′ and 3′ mean “five prime” and “three prime”, which indicate the carbon numbers in the DNA’s sugar backbone. The 5′ carbon has a phosphate group attached to it and the 3′ carbon a hydroxyl (-OH) group. This asymmetry gives a DNA strand a “direction”.
