The process of creating a collection of DNA fragments representing the entire genome of an organism.

Specialized DNA molecules used to carry and replicate foreign DNA fragments within host cells.

A technique for detecting and isolating specific DNA sequences from a gene library, using complementary probes.

The process of introducing foreign genes into host organisms in a way that allows the gene to be expressed and produce its protein product.

Techniques used to study the structure, function, and regulation of genes and their products.

The study of the complete set of genes and their interactions within an organism.

The study of how genetic variations influence individual responses to drugs.

The application of molecular biology techniques to create new products and processes in various fields, including medicine, agriculture, and industry.

A measure of the strength of an acid. The smaller the pKa value, the stronger the acid.

The form of a weak acid that has donated a proton (H+).

The form of a weak base that has accepted a proton (H+).

A weak acid that can donate more than one proton (H+) in a stepwise manner. Each ionization step has its own pKa value.

The process of a weak acid or base losing or gaining a proton (H+) depending on the pH of the solution.

A solution that resists changes in pH. It's often made by combining a weak acid and its conjugate base.

Separating molecules based on their charge. Weak acids and bases can be separated this way because their ionization changes with pH, affecting their charge.

Separating molecules based on their affinity for a charged surface. Weak acids and bases can be separated this way because their ionization changes with pH, affecting their charge.

A solution that resists changes in pH when small amounts of acid or base are added.

The Henderson-Hasselbalch equation is used to calculate the pH of a buffer solution, which depends on the ratio of the weak acid and its conjugate base.

The fractional ionization of a weak acid is the fraction of the acid that exists in its ionized form (as its conjugate base) in solution.

The pH of a solution determines the relative proportions of the protonated and deprotonated forms of a weak acid.

Buffer solutions are critical in biological systems because many biochemical molecules are weak electrolytes, meaning their ionization state changes with pH, creating a need for stable pH conditions to maintain proper function.

The degree of variation or scatter in a set of measurements, indicating how close the measurements are to each other.

The average value of a set of measurements.

A measure of how spread out the data is from the mean, calculated as the square root of the variance.

A measure of the precision of a set of measurements, expressed as a percentage of the mean.

A value that describes a characteristic of a population, such as the mean or standard deviation of the population.

A value that describes a characteristic of a sample, such as the mean or standard deviation of a sample.

The process of using a sample to estimate the characteristics of a population.

A statistical parameter that describes the precision of a measurement, taking into account both random and systematic errors.
