Explanation
## Step 1: Understanding the termsFirst, we need to understand what DNA, genes, and chromosomes are. - DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.- A gene is a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize.- A chromosome is a long, string-like structure that consists of nucleic acids and protein. It carries genetic information in the form of genes.## Step 2: Analyzing the optionsNow, let's analyze the options given in the question.- Option A suggests that chromosomes and proteins make up genes, and genes make up DNA. This is not correct as genes are part of DNA, not the other way around.- Option B suggests that chromosomes are made up of DNA and protein, and genes are sections of DNA on a chromosome. This is correct as it accurately describes the relationship between DNA, genes, and chromosomes.- Option C suggests that genes and proteins make up DNA, and the sequence of genes and proteins make up a chromosome. This is not correct as DNA is made up of nucleotides, not genes and proteins.- Option D suggests that proteins make up chromosomes and DNA, and DNA and chromosomes make up genes. This is not correct as it misrepresents the relationship between these components.
