Figure 5.19: Ribosomes translate RNA into a protein with a specific amino acid sequence.
The tRNA binds and brings to the ribosome the amino acid encoded by the mRNA. Ribo-
somes are made of rRNA and proteins. ( 6 )
Figure 5.20: This summary of how genes are expressed shows that DNA is transcribed into
RNA, which is translated in turn to protein. ( 13 )
