2 mar 2012 · This document discusses the structure, properties, and functions of DNA. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts.
Explore how DNA works, extract DNA, or transform DNA. Extract DNA from foods with just a few special materials in your own kitchen. Investigate how DNA works through hands-on biotechnology experiments or by finding patterns in free online databases.
28 lis 2015 · The document summarizes the structure of DNA. It describes that DNA is composed of four nucleotides - adenine, guanine, cytosine, and thymine. These nucleotides are linked by phosphodiester bonds to form a double helix structure.
Although each human has a unique DNA sequence, the DNA in all of us is about 99.9% identical! In this activity, you will use pieces of candy to make a model for a short section of DNA—enough to get a sense of what DNA is like and how it encodes life.
Introduce the molecular structure of DNA. What do you know about the components of a DNA molecule (nucleotides) and its shape? Again, listen to what students already know. Then use either of these two videos and the images provided in the Supplementary Materials to explain the structure of a DNA molecule. • DNA Structure • The Structure of DNA
Make a Self-Starting Siphon. Unlock the building blocks of life with genetics and genomics science experiments. Explore inheritance, DNA, and genetic variation. Discover the perfect middle school science experiment in this huge collection of age-appropriate science investigations.
For topics that involve complex molecules, like DNA, games work well to help students understand key concepts. The virtual lab simulation called DNA: Structure and function from Labster is a fun way to teach this topic. In this simulation, students can peer inside cells and see chromosomes.
