Biology
Protein Molecular Weight Calculator
Estimates the molecular weight of a protein from its amino acid count and average residue mass. Use it when designing proteins, interpreting SDS-PAGE results, or planning purification workflows.

Biology
Shannon Diversity Index Calculator
Compute the Shannon (Shannon-Wiener) diversity index H' for three species from their abundance counts. Higher values indicate greater diversity; 0 means a single-species community.
