DNA in the nucleus is packed into chromatin using proteins.Mitosis requires that the cell's chromatin be further packed into specific structures that are called chromosome which from a unique karyotype for each species.During mitosis the parent cell DNA is separated such that each daughter cell rec...
In the early part of the century, scientists searching for a chemical explanation of how the hereditary information is stored and used, were faced with a problem. It was known that chromosomes carried the genetic information, but it was not clear whether it was the DNA or the protein of ...
sex chromatin- chromatin found only in female cells; "the presence or absence of sex chromatin in cells obtained by amniocentesis makes it possible to determine the sex of a fetus" chromosome- a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; "humans...
So, the correct answer is A.Note:Genes are contained in chromosomes. These in the cell nucleus. A single chromosome contains hundreds to thousands of genes. Every normal human cell comprises 23 pairs of chromosomes that mean a total of 46 chromosomes. A trait is any gene...
INTRODUCTION Received 26.V.54 GENES within the nucleus are relatively unchanging, permanent hereditary units: they comprise the nuclear genotype. The chromo- somes which bear them, on the other hand, change considerably in behaviour and appearance. In this respect the nucleus presents a phenotypic ...
Confocal and electron microscopy images, and WB analysis of cellular fractions revealed that HP1γ is in the nucleus but also in the cytoplasm of C2C12 myoblasts, myotubes, skeletal and cardiac muscles, N2a, HeLa and HEK293T cells. Signal specificity was tested with different antibodies and by...
Function, chromatin packaging and spatial organization of the chromosomes The packaging and behavior of the chromosomes is central to the structure and function of the cell nucleus. The chromosomes play an important role in organizing the nuclear envelope around them after mitosis. A number of studies...

Investigating the chromatin states where fibrosis-associated DMPs were located, we found that compared to all probes present on the EPIC arrays, fibrosis-DMPs showed the strongest enrichment in regions annotated as enhancers in the human kidney (OR = 5.96, χ2 test P < 2.2 ×10-16;...
The STATs are set up in dimers and proceed to the nucleus where can bind to interferon-stimulated response element (ISRE) which modify the transcription of genes regulating proliferation, differentiation, and apoptosis of the cells [57,58]. Pieces of evidence state that the JAK/STAT pathway is...
