5 mrna strand 3
chains of nucleic acids have directionality and are read in a certain way just like languages are read from \left to right\ or
ight to left\.
dna is always read in the direction, whereas rna is read in the direction.
done

Explanation:

In nucleic - acid synthesis and reading, DNA is read by the enzyme DNA - dependent polymerases in the 3' to 5' direction for replication and transcription. RNA, including mRNA, is synthesized and read in the 5' to 3' direction during translation.

Answer:

DNA is always read in the 3' to 5' direction, whereas RNA is read in the 5' to 3' direction.
