Certainly! To put DNA, gene, and chromosome in order from smallest to largest, we need to understand their hierarchical relationship. Here's the order:
1. DNA: Deoxyribonucleic acid (DNA) is the smallest unit. It is a molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. DNA consists of nucleotides and is organized into structures called genes.
2. Gene: A gene is a segment of DNA that encodes a specific trait or function. It represents a sequence of nucleotides that provides the instructions for building proteins or performing other molecular functions. Genes are the basic functional units of DNA and determine various hereditary characteristics or traits.
3. Chromosome: A chromosome is a structure made up of DNA molecules tightly coiled many times around proteins called histones. It contains thousands of genes. Chromosomes are responsible for packaging DNA and ensuring its accurate distribution during cell division. They can be thought of as condensed threads of DNA.
So, the correct order from smallest to largest is: DNA, gene, chromosome.
