chromatinic

Thân thiện

The scientist examines the chromatinic material under the microscope.

Definition

1. Adjective:
   • (Biology) Relating to or having the properties of chromatin: Specifically describes the substance of a cell nucleus that is readily stained or colored by dyes used in microscopy.

Usage

• Adjective:
  • This term is used almost exclusively in cell biology and histology to describe the staining characteristics of nuclear material.
  • It is a technical descriptor for how cellular components interact with biological stains.

Examples

• Adjective:
  • The chromatinic material in the nucleus absorbed the dye intensely, making it clearly visible under the microscope.
  • Distinguishing between chromatinic and non-chromatinic regions is crucial for certain cytological analyses.

Advanced Usage

• "chromatinic granules": Refers to small, stainable particles within the nucleus.
  • The presence of abnormal chromatinic granules can be an indicator of cellular stress.

Variants and Related Words

• Chromatin (n): The complex of DNA and proteins (histones) that forms chromosomes within the nucleus of eukaryotic cells.

  • Chromatin condenses to form chromosomes during cell division.

• Chromatinic vs. Achromatic: "Chromatinic" describes material that stains readily, while "achromatic" describes structures (like certain parts of a microscope) that do not disperse color or stain.

Synonyms

• Stainable: Capable of being colored by a dye.
• Chromophilic: Having an affinity for stains (a more general term that can apply to structures outside the nucleus).

Antonyms

• Chromophobic: Resistant to staining; not readily colored by dyes.
• Achromatic: In biological contexts, can refer to structures that do not take up stain.
