Use the text to compare and contrast DNA and RNA.
When we think of genetics, DNA typically gets all the credit. Most people know that DNA
holds the genetic information used in the development and functioning of living
organisms. But did you know that RNA, like DNA, also holds this information? DNA is so
critical in the process of making new cells that it never leaves the nucleus of the cell.
Instead, it makes a copy of itself-RNA-which leaves the nucleus to do important work
like helping create proteins for the body. Think of DNA, which is composed of a double
helix, as a long-term storage facility for genetic information. RNA, on the other hand, is
composed of a single helix, and it can be thought of as a short-lived memo about a small
piece of the genetic code.
