What structure does mRNA have as it carries information to the ribosome? A) double stranded B) single stranded C) triple stranded

What the question is really testing

You are being asked to identify the physical structure of mRNA during its role in protein synthesis, specifically when it delivers genetic information to the ribosome.

How mRNA differs from DNA

• DNA is usually double stranded and stays mainly in the nucleus (in eukaryotes).
• mRNA is made from DNA during transcription, then it travels to the ribosome.

Picking the correct option

• A) double stranded: this describes typical DNA, not mRNA.
• B) single stranded: this matches how mRNA exists as it carries codons to the ribosome.
• C) triple stranded: not a standard structure for mRNA in normal cells.

Quick biology check

At the ribosome, the single-stranded mRNA is read in groups of three bases called codons, and tRNA anticodons pair with those codons to build a polypeptide.
