Where is the chromatin in the nucleus?
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 chromatin found in?
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.
What’s inside a nucleolus?
The nucleolus is the site of transcription and processing of rRNA and of assembly of preribosomal subunits. Thus it consists of ribosomal DNA, RNA, and ribosomal proteins, including RNA polymerases, imported from the cytosol.
What is chromatin state?
In the more general sense, the “chromatin state” of a genomic region can refer to the set of chromatin-associated proteins and histone modifications in that region. These are most often assayed by ChIP-seq, but also ATAC-seq, DNase-seq, ChIP-exo, and other methods.
Is chromatin found in plants or animals?
Chromatin is found in both plant and animal cells. The major difference between plant and animal cells is that plant cells have a cell wall and chloroplasts.
Is chromatin present in prokaryotes?
Prokaryotic cells do not have chromatin, instead, they have genophore, which is the prokaryotic equivalent. Read More: Prokaryotic Cells- Definition, Structure, Characteristics, and Examples. Differences Between Prokaryotic Cell and Eukaryotic Cell at BYJU’S.
