What is the structure of RNA called?
Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is then translated into proteins by structures called ribosomes.
What is the structure and function of RNA?

Structure | Short, unstable, single-stranded RNA corresponding to a gene encoded within DNA |
Function | Serves as intermediary between DNA and protein; used by ribosome to direct synthesis of protein it encodes |
What is the structure of RNA quizlet?
What is the structure of RNA? Single-stranded. Like DNA, RNA is composed of its phosphate group, five-carbon sugar (the less stable ribose), and four nitrogen-containing nucleobases: adenine, uracil (not thymine), guanine, and cytosine. You just studied 28 terms!
What types of structures can RNA form?
Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are important to its function.
What are RNA molecules?
Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), uracil (U), cytosine (C), or guanine (G).
What is structural difference between DNA and RNA?
So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
Does RNA have tertiary structure?
RNA molecules assemble into elaborate tertiary structures, forming globular shapes stabilized by networks of diverse interactions. Tertiary folded RNAs are recognized by proteins, ligands, and other RNA molecules, leading to biochemical events that impact every aspect of cellular metabolism.
