What is DNA?
DNA stands for deoxyribonucleic acid and is a code made up of four chemicals that store genetic information. DNA is passed down from parents to their children and contains specific instructions to build and maintain an organism's body. DNA contributes to a person's traits, such as eye color, hair color, and more.
Did you know?
The average human body contains enough DNA to stretch from the sun to Pluto and back — a distance of 5.4 billion miles! The human DNA contains 3 billion base pairs, but only 1-2% of them are actually genes that code for proteins -- the rest are 'non-coding' regions which are still important for various cellular processes. Different species of animals have different amounts of DNA. For example, the axolotl, a salamander, has 32 billion base pairs of DNA while humans have only 3 billion!

In a few words, what is DNA replication?
DNA Replication: Copying DNA for the Next Generation
DNA replication is a process of copying DNA before a cell divides. During the process, enzymes called DNA polymerases bind to DNA and create two identical copies. The copies will be passed on to the next generation, allowing living things to evolve.
DNA Replication: The process by which a cell copies its DNA in preparation for cell division. During replication, each strand of the DNA double helix is used as a template for the creation of a new complementary strand.
Semi-conservative Replication: A type of DNA replication in which the two strands of a DNA double helix separate, and each serves as a template for the formation of a new complementary strand.
Replication Fork: The point at which the two strands of a DNA double helix separate during DNA replication, forming a Y-shaped structure.
What is the purpose of DNA replication?
- To produce RNA molecules
- To generate proteins
- To create an exact copy of DNA
