The following six statements are steps in using bioinformatics to find potential cures for malaria, one of the most serious infectious diseases that humans face. The steps are not listed in the correct order below.
1. Computer modelling of candidate molecules to identify strong candidates
2. Determining the malaria parasite's proteome
3. Identifying candidate molecules that could inhibit malaria parasite enzymes
4. Sequencing the malaria parasite's genome
5. Drug trials to establish safety and efficacy
6. Identification of malaria parasite enzymes that could be targets
