To build a simple DNA model, make a double helix shape with beads, their color corresponding to the basic constituents of a DNA molecule: phosphate, sugar and base. Follow the correct order of how the parts of the DNA molecule are connected to each other.


A popular science fair project for younger children is to create a model of DNA using candy. To make this project, you need red licorice, black licorice, four different types of gummy candies, a needle, thread and toothpicks.


DNA, or deoxyribonucleic acid, is used in the human body in order for an organism to reproduce, develop and survive as well as in science for genetic engineering, forensics, bioinformatics, evolutionary history and information storage. A human's DNA code contains about 3 billion bases and 20,000 gen


The majority of DNA is located in the cell nucleus, where it is called nuclear DNA. A small amount is located in the mitochondria, where it is called mitochondrial DNA.


DNA is made of repeating units called nucleotides. The four nucleotides in DNA are adenine, cytosine, guanine and thymine. Adenine binds with thymine, and guanine binds with cytosine.


To make a double helix model of DNA out of candy, use toothpicks and colored marshmallows to create the base pairs and attach them to licorice strands to create the sugar and phosphate backbone. Once the model is constructed, twist both ends in opposite directions to resemble the double helix model.


DNA works by storing information that tells the body how to develop, survive and reproduce cells. DNA sequences are made up of four types of nucleotides: adenine, thymine, cytosine and guanine. Information in DNA is stored by the ordering of bonded nucleotides and resides in pieces of DNA called gen


The basic unit of DNA is a nucleotide. Each nucleotide consists of three portions: a phosphate group, a five-carbon sugar and a nitrogenous base. DNA uses four nitrogenous bases: adenine, thymine, guanine and cytosine.


DNA is located mainly in the nucleus, but can also be found in other cell structures called mitochondria. Since the nucleus is so small, the DNA needs to be tightly packaged into bundles known as chromosomes.


The full scientific name for DNA is deoxyribonucleic acid. Passed from adult organisms to their offspring, it contains the genetic instructions for the design of that organism.
