Here's why:
* DNA Structure: DNA is a long, complex molecule made up of two chains of nucleotides twisted into a double helix. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). The sequence of these bases forms the genetic code.
* Genetic Code: The specific order of the bases in DNA determines the sequence of amino acids in proteins. Proteins are essential for all cellular functions, making DNA the blueprint for life.
* Replication: DNA can replicate itself, ensuring that each new cell receives a complete copy of the genetic information.
* Inheritance: DNA is passed down from parents to offspring, carrying the genetic traits that make each individual unique.
While RNA plays a crucial role in protein synthesis, it's DNA that holds the master copy of the genetic instructions.
