Is RNA a single helix?
Understand the Problem
The question is asking whether RNA has a single helical structure. This pertains to biological and genetic concepts, specifically the structure of RNA compared to DNA.
Answer
RNA is usually single-stranded.
The final answer is RNA is usually single-stranded.
Answer for screen readers
The final answer is RNA is usually single-stranded.
More Information
RNA is typically single-stranded, allowing it to fold into various shapes needed for different biological functions. In some contexts, RNA can form double-stranded regions.
Tips
A common mistake is to assume that RNA and DNA are structured the same way; remember that DNA is double-stranded while RNA is usually single-stranded.
