- DNA is the genetic material, and therefore its structure and function
constitute the molecular basis of inheritance.
- When DNA replicates, two exact copies result. RNA structure is similar to, but also different from, that of DNA. RNA occurs in three forms, each with a specific function.
| - How does the structure of DNA allow it to function as the genetic material?
Answer
- How is RNA structure similar to, but also different from, that of DNA? What are the different forms of RNA?
