True or False: Human DNA is composed of a defined set of components that form patterns, and it is the patterns which give them meaning.

• A. False
• B. Not enough information
• C. Sometimes true
• D. True

Answer: (D)

DNA stores information in patterns formed by a defined set of components—the four nucleotides. Those patterns are read by the cell’s machinery: transcription copies the pattern into RNA, and translation uses that RNA to assemble proteins. The meaning of the pattern isn’t inherent on the bases themselves; it’s assigned by how cellular processes interpret and act on those patterns, determining which proteins are made, when, and where. So the statement is true: DNA is built from a defined set of components, and the patterns they form carry functional meaning through biological interpretation.
