Question

nucleic acids are assembled in the ___ direction.
2 to 3
5 to 1
5 to 3
1 to 5
4 to 5

Explanation:

Nucleic acids (DNA and RNA) are assembled in the \(5'\) to \(3'\) direction. This is because DNA polymerase (for DNA synthesis) and RNA polymerase (for RNA synthesis) add nucleotides to the \(3'\) -OH group of the growing nucleic acid chain.

Answer:

\(5'\) to \(3'\) (the option with \(5'\) to \(3'\) in the given choices)
