When living things eat, they take in ATP from their food. Adenine is an example of a nucleotide. During DNA replication, the cell makes a perfect copy every time. Codons are the three parts of a nucleotide. The different types of RNA are the same strand of RNA in different parts of the cell. There are three types of RNA involved in making proteins.
Understand the Problem
The question presents multiple statements about biology, specifically regarding DNA, RNA, and nucleotides, asking whether these statements are true or false.
Answer
Statements 12 to 17 are false. Statement 18 is true.
["Living things get ATP from metabolizing food, not directly. - False","Adenine is a nucleotide component (base), but not a nucleotide itself. - False","DNA replication aims to make perfect copies, but errors can occur. - False","Codons are made of three nucleotides. - False","Different RNA types (mRNA, rRNA, tRNA) serve different functions, not parts of the same strand. - False","There are three main types of RNA involved in protein synthesis. - True"]

More Information
Living organisms convert food into ATP through cellular respiration. Adenine is a base paired with other components to form nucleotides. DNA replication is generally accurate, but not always perfect. Codons are sequences of three nucleotides, and different RNA types have unique roles in protein synthesis.
Tips
Be careful not to confuse nucleotide components like adenine with complete nucleotides. Remember that DNA replication is high-fidelity but not error-free.
