Question

how do we note the \direction\ of a dna molecule? 5 and 3 north and south right and left rewatch

Explanation:

DNA is a double - stranded molecule. Each strand has a directionality. The direction of a DNA molecule is noted based on the carbon atoms in the sugar (deoxyribose) of the nucleotide. The 5' (five - prime) end has a phosphate group attached to the 5th carbon of the deoxyribose sugar, and the 3' (three - prime) end has a hydroxyl group (-OH) attached to the 3rd carbon of the deoxyribose sugar. This 5' - 3' directionality is crucial for processes like DNA replication (where DNA polymerase adds nucleotides in the 5' - 3' direction) and transcription. North, South, right, and left are not relevant terms for indicating the direction of a DNA molecule.

Answer:

5' and 3'
