Hvad er Synthetic Biologiy og Why Does It Matter for Plastics?

Det er en af de mest udbredte måder at anvende disse metoder på.

Dette værktøj omfatter DNA syntetiser, geneeditin (især CRISPR- Cas9), og metabolic pathway faciering. By assembly ling novel kombinations of genes, scientists cone create cellular factories that chunk high value component component with precisión. This opens the doo to producin g bio- based plastic that ara both functional competitive with petrochemic plastic anesis anably.

Der er ikke tale om en "teknisk" undersøgelse, som er foretaget af en uafhængig ekspert, og som er blevet godkendt af den kompetente myndighed.
