DNA Structure and Function – Study
Notes
Introduction
DNA stands for Deoxyribonucleic Acid. It is the molecule that stores the genetic information
of all living organisms.
DNA determines many characteristics of an organism, such as:
- The color of our hair
- Our height
- Which proteins are produced in the body
In simple terms, DNA acts as the instruction manual of life.
Discovery of DNA
Scientist Contribution
Friedrich Miescher Discovery of DNA
James Watson Proposed DNA structure
Francis Crick Developed the Double Helix Model
In 1953, Watson and Crick proposed the DNA Double Helix Model.
Structure of DNA
The structure of DNA resembles a double helix, which looks like a twisted ladder.
The main components of DNA are:
1. Deoxyribose Sugar
2. Phosphate Group
3. Nitrogenous Bases
Base Pair
Adenine (A) Thymine (T)
Guanine (G) Cytosine (C)
