Hey guys I'm new to this forum and I need help! I'm answering some micro questions for uni and I have a few questions I can't answer (I've tried looking for answers everywhere!) They might be stupid questions and I'm not exactly the smartest person so here goes....
1: Explain how bacteria can grow large colonies on starch agar but not necessarily produce amylase.
2. DNases are too large to be taken up by cells, so they would not be effective against DNA within cells. What do you think is the source of DNA when these organisms are in their natural environment?
3. Some pathogens produce proteases and lipases. How might these enzymes contribute to their ability to cause disease?
