Michiko Taga, first author on the paper (also based at MIT), began searching for the genes that might be playing a role in the final stages of B12 synthesis, assuming that BluB was one of several proteins working to create DMB.

It follows that your ability to write syntheses depends on your ability to infer relationships among sources - essays, articles, fiction, and also nonwritten sources, such as lectures, interviews, observations.

Buchwald phosphine ligands for C-C, C-N, and C-O bond formation.

What is a synthesis.

The UV-Vis spectrum of each complex would identify different properties and would help to explain the observations made when they were synthesized (for example their colour and how they reacted).
