Question

Which of the following best describes the functional significance of the sugar-phosphate backbone in RNA?

Options

• It replaces the function of nitrogenous bases

• It carries the genetic information directly

• It provides structural support and flexibility to the RNA molecule

• It catalyzes protein synthesis independently

Answer 1

The backbone of RNA, composed of alternating ribose sugar and phosphate units, provides structural support to the RNA molecule. This backbone maintains the chain integrity and contributes to the flexibility of the single-stranded RNA structure, allowing it to form various three-dimensional configurations necessary for its diverse biological functions.
