Understanding DNA: The Basics
Before diving into the Gizmo student exploration, it is essential to comprehend what DNA is and why it is significant in biological science.
What is DNA?
DNA (deoxyribonucleic acid) is the hereditary material in all known living organisms and many viruses. The key features of DNA include:
- Structure: DNA is composed of two long strands that form a double helix. Each strand consists of nucleotides, which are the building blocks of DNA.
- Nucleotides: Each nucleotide contains three components: a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base. The four types of nitrogenous bases are adenine (A), thymine (T), cytosine (C), and guanine (G).
- Base Pairing: In the double helix structure, adenine pairs with thymine, and cytosine pairs with guanine, held together by hydrogen bonds.
Understanding DNA is crucial for numerous fields, including genetics, forensic science, and biotechnology.
