DNA Structure and Replication Overview
DNA (deoxyribonucleic acid) is a molecule that carries genetic information in the form of a code made up of four chemical bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up with each other to form base pairs, which are the building blocks of DNA.
The sequence of these base pairs encodes the genetic information that is passed on from parents to offspring.
DNA replication is the process by which a cell makes a copy of its DNA before cell division. This process ensures that each new cell has a complete copy of the genetic information.

Top FAQs: Dna Structure And Replication Worksheet Answer Key Pdf
What is the significance of DNA replication?
DNA replication ensures the accurate transmission of genetic information during cell division, ensuring the continuity of life and the preservation of species characteristics.
How does DNA polymerase contribute to DNA replication?
DNA polymerase is the key enzyme responsible for synthesizing new DNA strands during replication. It reads the template strand, adds complementary nucleotides, and proofreads the newly synthesized strand to maintain accuracy.
