  8. Sequenciamento de DNA (artigo) | Khan Academy

    A sequenciação de DNA é o processo através do qual se determina a sequência das bases (As, Ts, Cs e Gs) num fragmento de DNA. Atualmente, com o equipamento e materiais certos, sequenciar uma …

  9. Gel electrophoresis (article) | Khan Academy

    Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another. We can also determine the absolute size of a piece of DNA by …

  10. RNA and protein synthesis review (article) | Khan Academy

    The first step in decoding genetic messages is transcription, during which a nucleotide sequence is copied from DNA to RNA. The next step is to join amino acids together to form a protein.
