english: To explain what microRNAs are and their important role in cancer, I need to start with proteins, because when cancer is present in our body, protein modification is observed in all cancerous cells.
non_english: Kako bismo objasnili šta je mikroRNK i njenu značajnu ulogu za rak moram da krenem od proteina, jer kad je rak prisutan u našem telu posmatra se modifikacija proteina u svim kancerogenim ćelijama.
