O que é o DNA?
+
+
DNA , substância química orgânica de estrutura molecular complexa encontrada em todas as células procarióticas e eucarióticas e em muitos vírus . Cada fita de uma molécula de DNA é composta por uma longa cadeia de nucleotídeos. Os nucleotídeos do DNA consistem numa molécula de açúcar desoxirribose à qual está ligado um grupo fosfato e um dos quatro grupos nitrogenados:
- adenina e timina
- citosina e guanina.
O que é a CRIsPR-CAS9?
+
+
Um dos avanços mais recentes na área da biotecnologia foi o desenvolvimento do sistema CRISPR-Cas9.
É constituído por:
- ma enzima (endonuclease Cas9) que corta a dupla cadia de DNA num local específico
- RNA guia (CRISPR) complementar da sequência de DNA que se pretende cortar
+
+
Este sistema foi descoberto em bactérias que usam o sistema CRISPR-cCas9 para se protegerem de virus, quebrando o DNA viral e inativando-o. E permite a edição de DNA, em particular de sequências génicas, de forma a silenciar a expressão ou alterar a proteína codificada pelo gene específico. Para tal, os cientistas produzem uma molécula de RNA guia, que se liga á Cas9 e que procura no genoma a sequência que lhe é complementar e que se pretende alterar
Em outubro de 2020, o mundo conheceu os vencedores do prêmio Nobel de química de 2020: duas cientistas, Dra. Jennifer Doudna e Dra. Emmanuelle pelo desenvolvimento de uma técnica de edição de genes chamada CRISPR-Cas9
Aplicações no dia a dia
+
+
Como funciona?
+
+
Imaginem que se quer mudar uma secção de um DNA porque ele apresenta uma mutação que causa uma doença. Os cientista vão criar uma cópia desta secção( RNA mensageiro guia ) e vão liga-la à proteína Cas9. A Cas9 junto com com a secção de RNA guia, é inserida na célula e vai à procura do “match” no DNA (a secção que é igual), quando ela encontra faz o papel de uma tesoura e corta essa secção.Depois disso vai ser possível inserir uma nova sequência no lugar, ou até mesmo deixar a própria célula arranjar aquela secção de DNA sozinha.
