DNA → protein translator Convert DNA or RNA sequences into amino acid chains with codon table annotations. DNA concentration calculator Normalize A260 readings to ng/µL, molarity, and copy number with dilution options. Hemocytometer counter Convert grid counts into cells per mL with dilution factors and viability tracking. Cell doubling time Estimate population doubling for exponential growth or decay phases. Bacterial growth curve Model lag, exponential, stationary, and death phases using OD or cell counts. Allele frequency calculator Track allele and genotype frequencies with Hardy–Weinberg and selection options. Hardy–weinberg equilibrium Evaluate equilibrium assumptions, chi-square tests, and allele shifts. Punnett square generator Visualize monohybrid or dihybrid crosses with genotype and phenotype ratios. Restriction digest planner Design single or double digests with enzyme compatibility and fragment prediction. Michaelis–menten calculator Fit enzyme kinetics, Km, Vmax, and Lineweaver–Burk transformations. Lotka–volterra simulator Explore predator–prey population dynamics with adjustable interaction rates. Island biogeography Estimate equilibrium species richness from colonization and extinction rates. Niche breadth calculator Measure ecological niche width using Levin’s or Shannon diversity indices. Population pyramid generator Create age–sex demographic charts from raw counts or normalized proportions. Life table calculator Compute survivorship (lx), mortality (qx), and life expectancy (ex) metrics. Fick's law diffusion Calculate flux through membranes using concentration gradients and diffusion areas. Related categories Science Calculators Health & Fitness Math & Conversions Chemistry Tools
