The Ribosomes synthesize proteins and lipids

A. anticodon: An anticodon is a three-nucleotide sequence on transfer RNA (tRNA) that is complementary to the codon on messenger RNA (mRNA). Anticodons allow tRNA to bring the correct amino acid to the ribosome during protein synthesis, but they are not located on DNA and do not directly code for amino acids.

B. primer: A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis during replication. It is not a coding sequence for amino acids, but rather a temporary sequence used by DNA polymerase to initiate replication.

C. exon: An exon is a segment of DNA or mRNA that contains coding information for proteins. While exons are part of the gene that is ultimately expressed, the term does not specifically refer to a three-base sequence that codes for a single amino acid.

D. intron: An intron is a noncoding segment of DNA within a gene that is transcribed into RNA but removed during mRNA processing. Introns do not code for amino acids and are not involved in specifying the protein sequence.

E. triplet: A triplet, also known as a codon when transcribed into mRNA, is a sequence of three nucleotides on DNA that specifies a single amino acid during protein synthesis. Each triplet corresponds to one amino acid in the growing polypeptide chain, forming the genetic code.

When a control agent targets metabolic processes, actively growing and metabolizing cells are more susceptible than older or dormant cells. Younger microbial cells have higher rates of enzyme activity, protein synthesis, and energy production, which are the pathways most affected by metabolic inhibitors. In contrast, older or stationary-phase cells have slowed metabolism and often possess stress adaptations that make them less vulnerable to these agents. Therefore, treatments that disrupt metabolism such as certain antibiotics or chemical disinfectants tend to kill actively dividing cells more rapidly, while non-dividing or metabolically inactive cells survive longer.
