A estrutura do DNA

Un tutoriais interativo e animado criado pelo Eric Martz
Adaptado ao uso do J(S)mol pelo Angel Herráez
Parte do Web site Biomodel de Angel Herráez, Univ. de Alcalá (Espanha)

A. A dupla hélice do DNA: pareamento de bases e pontes de hidrogênio	B. O código genético e a replicação do DNA Explicaçao de códons e anticódons
C. A estrutura das fitas e o "esqueleto" de fosfato/desoxi-ribose	D. As extremidades 5' e 3' e o antiparalelismo das fitas

This tutorial is designed to complement Biology or Biochemistry and Molecular Biology books, so it is not by itself a complete introduction to DNA structure.

Set preference whether or not to use Java in these pages
Autodetection suggests your system is ?.
Therefore, by default the ? modality will be used.

I do not have Java or
I prefer not to use it.

Whenever possible, the use of the swifter Java modality is recommended, particularly with Internet Explorer.
2. This tutorial is designed to complement an introduction to DNA, by providing tools for a self-directed exploration. It does not tell a story (but does offer questions for students and a lesson plan for teachers). As a preamble to the tutorial below, or for a story that introduces DNA structure with interactive molecular graphics, we recommend
   • DNA Structure in Biomodel-3 (basic level, adequate for secondary school).
   • DNA Structure in Biomodel-1 (advanced level).
   • Exploring DNA Structure by Andrew Carter (Jmol version by Frieda Reichsman).
   • Other DNA links.
3. Páginas do tutoriais animado interativo (A, B, C, D): please visit the 4 sections in the colored panels.
4. Questions for Students and a Lesson Plan for Teachers.
   More Molecules for High School Teachers.
5. More DNA Resources includes tutorials for high school students, college freshmen, interactive Shockwave simulations of agarose gel electrophoresis to learn about electrical charge of DNA, cutting with restriction endonucleases, etc.
