questions for a biology crossword…?
1) a stubstance prepared from killed or weakened pathogens and introduced into a body to produce immunity
2) describes a microorganism or virus that causes disease and that is highly infectious
3) an enzyme that catalyzes the formation of the DNA molecule
If this is for a crossword, you really should have given us the number of letters for each clue! As is, I’ll guess:
1. antibody, serum, vaccine
2. pathogen, pathogenic
3. polymerase, dna polymerase
