The correct Answer is:
To arrange the given biological entities in order of increasing size, we need to understand the hierarchy of genetic material. Here’s a step-by-step breakdown: ### Step 1: Identify the smallest unit The smallest unit in the hierarchy is the **nucleotide**. Nucleotides are the building blocks of nucleic acids (DNA and RNA) and consist of a nitrogenous base, a sugar, and a phosphate group. **Hint:** Think of nucleotides as the basic units that make up larger structures. ### Step 2: Move to the next level The next level up from nucleotides is the **gene**. A gene is a segment of DNA that encodes for a specific protein or function. Genes are made up of sequences of nucleotides. **Hint:** Remember that genes are composed of multiple nucleotides. ### Step 3: Continue to the next level Next, we have **chromosomes**. Chromosomes are structures within cells that contain many genes. They are made up of tightly coiled DNA and proteins. In humans, for example, there are 46 chromosomes. **Hint:** Think of chromosomes as packages that contain many genes. ### Step 4: Identify the largest unit Finally, the largest unit is the **genome**. The genome is the complete set of genetic material in an organism, including all of its chromosomes. In humans, the genome consists of approximately 3 billion base pairs across 46 chromosomes. **Hint:** The genome encompasses all the genetic information, including all chromosomes. ### Final Arrangement Now, we can arrange these entities in order of increasing size: 1. Nucleotide 2. Gene 3. Chromosome 4. Genome ### Conclusion The correct order of increasing size is: - Nucleotide - Gene - Chromosome - Genome ### Answer The correct option is: **Nucleotide, Gene, Chromosome, Genome.**
