Question

An m R N A strand has the following sequence: C A G A U G U A C G G A C G A U A A.
Chains of nucleic acids have directionality and are read in a certain way just like languages are read from "left to right" or "right to left."

DNA is always read in the
direction,
whereas RNA is read in the
direction.

Answer 1

DNA is read 3′ → 5′, whereas RNA (mRNA) is read 5′ → 3′.

Explanation: RNA polymerase reads the DNA template strand in the 3′→5′ direction to synthesize RNA 5′→3′, and the ribosome reads mRNA in the 5′→3′ direction during translation.
