Colour the individual structures on the worksheet as follows: adenine = red thymine = green guanine = blue cytosine = yellow phosphate = brown deoxyribose = purple. Cut out each structure. Using the small symbols (squares, circles and stars) on the structures as guides, line up the bases, phosphates and sugars.
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).
1. What does DNA stand for? 2. Where do you find DNA in living things? 3. What is the function of DNA? During-lab observations: Label the DNA model diagram below. P = Phosphate, S = Sugar (deoxyribose), A, T, C, G = Bases.
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 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.
Students will construct a DNA model, describe the structure and function of DNA, sequence the steps involved in DNA replication, and plan and design a model of DNA. This lesson should be done after a lesson on the structure and function of cells.
DNA is composed of six different subunits (or smaller molecules): Guanine (a base) Phosphate group Thymine (a base) Deoxyribose (a sugar) Adenine (a base) Cytosine (a base)
