Question

The Coding Strand is also known by which alternative names?

Options

• Antisense strand, Non-coding strand, Minus (−) strand

• Sense strand, Non-template strand, Plus (+) strand

• Template strand, Promoter strand, Exon strand

• mRNA strand, Intron strand, Terminator strand

Answer 1

The Coding Strand, which does NOT serve as the template for RNA synthesis, is also called the Sense strand because its sequence is the same as the mRNA (except T → U). It is referred to as the Non-template strand and the Plus (+) strand due to its 5' → 3' polarity, which is the conventional direction of DNA sequence representation.
