Question

multiple choice question
rna plays a critical role in the development of cellular structure because ______.

all three types of rna contribute to protein synthesis
it is the storage molecule for genetic information
atp is both an energy storage molecule and a part of rna
it must be contained within a lipid bilayer to be functional
need help? review these concept resources.
read about the concept

Explanation:

• DNA, not RNA, is the primary genetic information storage molecule, eliminating the second option.
• ATP's role as an energy molecule and relation to RNA does not explain RNA's role in cellular structure development, eliminating the third option.
• RNA can function outside a lipid bilayer (e.g., in translation), eliminating the fourth option.
• The three main RNA types (mRNA, tRNA, rRNA) all directly participate in protein synthesis; proteins are the main structural components of cells, so this explains RNA's critical role in cellular structure development.

Answer:

all three types of RNA contribute to protein synthesis
