The 5' prime end of each DNA strand is characterized by a phosphate group attached to the fifth carbon of the sugar molecule in the DNA backbone. This phosphate group distinguishes the 5' end from the 3' end, which has a hydroxyl (-OH) group attached to the third carbon of the sugar. Therefore, the 5' end is essential for the directionality of DNA synthesis and affects how the DNA strand interacts with enzymes during replication and transcription.
