Understand the concept of a codon: A codon is a sequence of three nucleotides on mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.
Review the role of mRNA in protein synthesis: mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
Examine the structure of a codon: Each codon consists of three nucleotides, which are the building blocks of RNA and DNA.
Clarify the function of codons in protein synthesis: Codons are crucial for translating the genetic code into proteins, with each codon specifying a single amino acid or a stop signal.
Identify the incorrect statement: A codon cannot code for multiple amino acids; each codon is specific to one amino acid or a stop signal, ensuring precise protein synthesis.
