Biology Calculators

Streamline genetics, microbiology, ecology, and biochemistry workflows with calculators that document formulas, guidance, and accepted references.

Convert DNA or RNA sequences into amino acid chains with codon table annotations.

Normalize A260 readings to ng/µL, molarity, and copy number with dilution options.

Convert grid counts into cells per mL with dilution factors and viability tracking.

Estimate population doubling for exponential growth or decay phases.

Model lag, exponential, stationary, and death phases using OD or cell counts.

Track allele and genotype frequencies with Hardy–Weinberg and selection options.

Evaluate equilibrium assumptions, chi-square tests, and allele shifts.

Visualize monohybrid or dihybrid crosses with genotype and phenotype ratios.

Design single or double digests with enzyme compatibility and fragment prediction.

Fit enzyme kinetics, Km, Vmax, and Lineweaver–Burk transformations.

Explore predator–prey population dynamics with adjustable interaction rates.

Estimate equilibrium species richness from colonization and extinction rates.

Measure ecological niche width using Levin’s or Shannon diversity indices.

Create age–sex demographic charts from raw counts or normalized proportions.

Compute survivorship (lx), mortality (qx), and life expectancy (ex) metrics.

Calculate flux through membranes using concentration gradients and diffusion areas.
