The document provides information about RNA structure and function. It discusses the components of RNA nucleotides, the three main types of RNA (mRNA, tRNA, rRNA), their structures and roles. mRNA carries codes from DNA in the nucleus to the cytoplasm. tRNA transports amino acids to the ribosome. rRNA forms the ribosomal subunits where protein synthesis occurs.

11. E. VISUAL ANALOGY
The master plan of a building shows how to build and place important parts of the
building, such as walls, pipes, and electrical outlets. On the building site, workers use
copies of the master plan called blueprints to show them what to do. The master plan is
kept in the office. Explain how mRNA works like a blueprint in constructing proteins.

The master plan is the DNA molecule. The cell uses this molecule to prepare mRNA
“blueprints.” The mRNA carries the instructions for protein synthesis from the nucleus to
the ribosomes in the cytoplasm, where the proteins are built.
