Tips for next year
- Think about the order in which you do your assemblies. Short pieces of DNA tend to be hard to manipulate experimentally. Plan your assembly such that you cut out the large fragments from plasmids and leave the small fragments as part of the plasmid.
- Using more cells in your bacterial photograph seems to lead to poorer contrast but better resolution.
