Exam: GRE (Verbal)

Definition: A substance or organism that can produce a pigment or dye, often used in biological and chemical contexts.

Example: The scientist studied the chromogen to understand how it generates color in the cells.

Definition: Relating to a process that produces color or involves color changes, especially in photography.

Example: The chromogenic film produced vibrant colors in the photographs.

Definition: A small, bead-like structure made of chromatin that is found on a chromosome during cell division.

Example: During the cell division process, chromomeres can be observed as distinct granules along the chromosomes.

Definition: A coiled structure found in chromosomes that contains genetic material and is part of the chromatid.

Example: During cell division, the chromonema becomes visible as the chromosomes condense.

Definition: Easily colored or stained by dyes, often used to describe cells or structures in biology that absorb color.

Example: The chromophil cells in the tissue sample showed vibrant colors under the microscope.

Definition: A type of cell or cell structure that has an affinity for staining or coloring, often used in biological contexts to describe cells that readily absorb dyes.

Example: The chromophil cells in the tissue sample showed vibrant colors under the microscope.

Definition: Not easily stained by dyes, often referring to cells or structures that do not absorb color when treated with staining agents.

Example: The chromophobe cells in the tissue sample did not take up the dye during the experiment.

Definition: A part of a molecule that can absorb light and gives color to that molecule.

Example: The chromophore in the dye is responsible for its bright red color.

Definition: Relating to a substance that can absorb light and produce color.

Example: The chromophoric properties of the dye make it suitable for various applications in art and science.

Definition: A type of protein that has a colored group attached to it, which gives it a specific color and function, like hemoglobin in blood.

Example: Hemoglobin is a chromoprotein that carries oxygen in the blood.

Definition: Relating to the structures in cells that carry genetic information.

Example: The chromosomal abnormalities can lead to various genetic disorders.
