Modeling the Structure of DNA student handout. 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).
Build a Paper Model of DNA. Fill in the names of the bases on the model shown to the right, or use the detailed model that shows all the atoms in each nucleotide (back side of paper). Cut out the model. Fold all long creases first.
DNA (kwas dezoksyrybonukleinowy) jest cząsteczką chemiczną o kształcie podwójnej, prawoskrętnej helisy (w uproszczeniu – skręconej drabiny. Nogi drabiny to szkielet cząsteczki, a szczeble – to zasady, dzięki którym całość trzyma się razem).

flow of genetic information from DNA to protein. But first, in this chapter we look closely at the structure and chemistry of DNA in order to learn how its double-helical architecture allows information to be stored, duplicated, and accessed. Each DNA strand is an alternating copolymer of phosphates and deoxyribose sugars
Using the small symbols (squares, circles and stars) on the structures as guides, line up the bases, phosphates and sugars. Glue the appropriate pairs together to form nucleotides. Construct the right side of your DNA molecule by putting together in sequence a cytosine, thymine, guanine and adenine nucleotide.
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.
