The Structure and Function of DNA: Blueprint of Life

Deoxyribonucleic Acid (DNA) serves as the fundamental blueprint for all living organisms, composed of nucleotides that link together to form DNA chains. All living things share the same basic DNA structure, which belongs to the nucleic acids family. DNA consists of four bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) that pair specifically (A with T and G with C). This intricate structure not only encodes genetic information but also allows for replication, where the DNA ladder unzips and free-floating nucleotides form new strands.

Presentation Transcript

  1. Deoxyribonucleic Acid DNA

  2. … is the blueprints or instructions for all living things. • … has the same basic structure for all living things • … belongs to a group of complex molecules known as Nucleic Acids. DNA… All nucleic acids including DNA are composed of Nucleotides

  3. Nucleotides What DNA is made of?

  4. Nucleotides • There are four different kinds of bases • Adenine • Thymine • Guanine • Cytosine

  5. Nucleotides • Nucleotides combine to form DNA chains • A to T, C to G rule • Adenine always combines with Thymine A-T • Guanine always combines with Cytosine C-G

  6. DNA Ladder

  7. Who discovered it

  8. They didn’t do it alone

  9. How did they do it?

  10. DNA Ladder

  11. How does it copy

  12. DNA ladder unzips

  13. Free floating Nucleotides connect

  14. Two New Strands
