B) codon
C) organelle
D) cell

Question

Quizplus · Accepted Answer

A codon is the smallest unit of genetic code that consists of three nucleotides, whereas a gene is a sequence of many codons that codes for a protein. An organelle is a membrane-bound structure within a cell that performs a specific function, which is larger than a gene or a codon. A cell is the smallest unit of life that can survive independently, which contains organelles, genetic material, and other biomolecules, hence it is larger than a gene, codon, or organelle. Therefore, the smallest structure among the given options is a codon.
