Why is chromatin formed?
Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures.
What cells is chromatin in?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
What is the meaning of chromatin?
Chromatin. =. Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Changes in chromatin structure are associated with DNA replication and gene expression.
When did Walther Flemming discover chromatin?
Walther Flemming discovered chromatin in 1880. He observed the fibrous network present in the nucleus and termed it chromatin (stainable material). Stay tuned to BYJU’S to learn similar questions and important points related to chromosome structure and functions.
What is the role of chromatin in DNA replication?
The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Changes in chromatin structure are associated with DNA replication and gene expression. Chromatin is the material that makes up a chromosome that consists of DNA and protein.
What are histone proteins found in eukaryotic chromatin?
Histone proteins and DNA are found in approximately equal mass in eukaryotic chromatin, and nonhistone proteins are also in great abundance. The basic unit of organization of chromatin is the nucleosome, a structure of DNA and histone proteins that repeats itself throughout an organism’s genetic material.
