Estructura del ADN y su Replicación

El ADN es básicamente el disco duro de la vida. Contiene toda la información genética que necesitas para funcionar y desarrollarte, pero no puede hacer el trabajo solo: necesita al ARN como su compañero de equipo para transmitir la información desde el núcleo hasta el citoplasma.

Imagínate el ADN como una escalera de caracol gigante formada por pequeñas piezas llamadas nucleótidos. Cada nucleótido tiene tres partes: ácido fosfórico, desoxirribosa y una base nitrogenada (adenina, guanina, citosina o timina). Lo genial es que estas bases se emparejan siempre de la misma manera: adenina con timina, y guanina con citosina.

El ARN es diferente porque tiene una sola cadena en lugar de dos, y usa uracilo en vez de timina. Hay tres tipos importantes que debes conocer: el ARNm que copia la información del ADN, el ARNt que transporta aminoácidos, y el ARNr que forma parte de los ribosomas donde se fabrican las proteínas.

💡 Dato curioso: Watson y Crick descubrieron la estructura de doble hélice del ADN, ¡pero fue gracias a los datos de Rosalind Franklin que pudieron hacerlo!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
