Definition: A substance found in the nucleus of cells, made of DNA and proteins, that helps package and organize genetic material. It can change shape during cell division to form chromosomes.

Example: During cell division, chromatin condenses to form visible chromosomes.

Definition: Relating to chromatin, which is a complex of DNA and proteins found in the nucleus of cells that helps package DNA into a more compact form.

Example: The chromatinic structure of the cell plays a crucial role in gene regulation.

Definition: A visual representation showing the different substances that have been separated during a chromatography process.

Example: The scientist analyzed the chromatogram to identify the components of the mixture.

Definition: A device used to separate and analyze different components in a mixture, producing a visual representation of the results.

Example: The scientist used a chromatograph to analyze the chemical composition of the sample.

Definition: To use a method for separating and analyzing substances in a mixture.

Example: Scientists often chromatograph samples to identify their components.

Definition: Relating to a method used to separate mixtures into their individual components, often used in chemistry and biology.

Example: The chromatographic technique allowed the scientists to analyze the different substances in the sample.

Definition: A method used to separate different substances in a mixture based on how they interact with a moving liquid or gas and a stationary material.

Example: The scientist used chromatography to analyze the components of the chemical mixture.

Definition: The process where certain materials in a cell, especially chromatin, break down or dissolve.

Example: During chromatolysis, the cell's chromatin disintegrates, affecting its function.

Definition: A type of cell that contains pigment and can change color by expanding or contracting, found in some animals like lizards and in certain bacteria.

Example: The chameleon can change its color thanks to the chromatophores in its skin.

Definition: Relating to or containing the chemical element chromium, particularly in its trivalent form.

Example: The chromic acid solution is used in various industrial processes.

Definition: The difference between a color and a reference color that has the same brightness, often used in color television and imaging.

Example: In video processing, chrominance is important for accurately representing colors.
