DNA is like a book because the arrangement of nucleotides in the DNA determines the entire organism’s phenotype.
Further Explanation:
Gene is defined as the linear sequence of the nucleotides that are mainly encoded for a protein having a particular function. The alleles are defined as the variant type of the gene. DNA is mainly made up of the nucleotides and also contains genetic information in the genes. Every nucleotide mainly comprised of the phosphate group, deoxyribose, and nitrogenous base. DNA is mainly composed of four distinct types of nitrogenous base:
The letters in the book are similar to the nucleotide in the DNA. The meaningful combination of letters forms the information that is entitled. Similarly, the arrangement of nucleotides in the DNA is responsible for the structural and functional behavior of the organism. That’s why DNA is considered as a book that enclosed all the hereditary information of the body.
