Which of these combinations identifies the appropriate labels in the order as shown in the diagram (1,2,3) ? (SC.7. DNA, chromosome, gene chromosome, gene, DNA DNA, gene, chromosome chromosome, DNA, gene

To determine the correct combination of labels in the order shown in the diagram, we need to understand the hierarchy of genetic structures.<br /><br />1. DNA (Deoxyribonucleic Acid) is the molecule that carries genetic information in living organisms. It is the fundamental building block of genes and chromosomes.<br /><br />2. Gene is a segment of DNA that codes for a specific protein or trait. Genes are the basic units of heredity and are responsible for determining the characteristics of an organism.<br /><br />3. Chromosome is a structure that contains a long, continuous thread of DNA. Chromosomes are found in the nucleus of cells and carry genes.<br /><br />Based on this hierarchy, the correct combination of labels in the order shown in the diagram is:<br /><br />DNA, gene, chromosome<br /><br />Therefore, the correct answer is: DNA, gene, chromosome.
