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.
INTRODUCTION. In this activity, you will build your own model to understand how DNA works. DNA is a simple molecule made up of four types of chemical building blocks called nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
9 lut 2014 · It describes the key components of DNA including the sugar-phosphate backbone, nitrogenous bases, and how the bases pair up in the double helix structure. It also discusses different DNA structures like A, B and Z-DNA and how DNA packages into nucleosomes and chromosomes.
Bring the structure of DNA to life for your middle school science students with this resource that would make Watson, Crick AND Franklin proud. In this lesson, students learn the history of DNA discovery, demonstrate how nucleic acids pair with one another, and observe DNA with the naked eye.
DNA Structure. 1. LESSON: What is the structure of DNA? I use a powerpoint lesson to introduce the topic with my students. You can find it on my website or on TpT. 2. MODELS: It’s fun to have students build some sort of model. Here is a template that I use to have students build models out of paper.
DNA is a polymer of nucleotide monomers, each consisting of a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). The nucleotides of DNA are arranged into a double helix based on the rules of base complementarity.
This completely digital product includes a PowerPoint presentation, accompanying illustrated student guided notes, and 3 pages of review worksheets, and will provide students with a thorough introduction to the structure of the DNA double helix and the basic steps of DNA replication.
