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.
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.
Chromosomes are microscopic, threadlike strands composed of the chemical DNA (short for deoxyribonucleic acid). In simple terms, DNA controls the production of proteins within the cell. These proteins in turn, form the structural units of cells and control all chemical processes within the cell.
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.
Biology I: Unit 2 (A DNA Mastery Unit) – Worksheet 1: DNA Structure 1. What do the letters DNA stand for? _____ 2. Two scientists are given credit for discovering the structure of DNA. What is the name of those two scientists. a. _____ b. _____ 3. DNA is a polymer, which means that is made up of many
11 maj 2017 · 1 of 58. 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.
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).
