We all (from the left Arno Melgiovanni, Silvia Calò,Giuseppe Rizzo, Paola Vivoli, Lavinia Di Prima, Alessia Pillitteri) are attending a biotechnology course at university, that will help us in orientieering if we really want to choose Biology in the next future.
We have to take part to 5 meetings of four hours each on Thursdays at 2.30 am. During these meetings we have been following lessons made up by lecturer Vittorelli and the others teaching fellows; afterwards we perform different trial proofs.
1st meeting.
When we arrived they gave us gowns and books which would have helped us following the lessons and performing the trials proofs. The lessons were about the prokaryotic and eukaryotic cells and others microorganisms. Then we went to the laboratories and made bacteria coltures.
2nd meeting.
This time the lessons were about P.C.R., that is a scientific technique in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. In laboratories we also did it ourselves.
3rd meeting.
The lessons were about the gel electrophoresis, that is a technique used for the separation of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or protein molecules using an electric field applied to a gel matrix. In laboratories we did also that one ourselves.
4th meeting.
The lessons were this time about the structure and the duplication of DNA, besides also about the leaching of human DNA. Indeed we managed to draw out our own DNA from our spit.
We haven’t done the 5th meeting jet, so we can’t tell you about that one, but we are sure that it will be as interesting as the previous ones.
