What is the difference between chromatin and chromatid? Chromosomes: A chromosome is a structure in the nucleus tightly packaged with DNA. The DNA is supported by histones around which it is coiled. The chromosomes are vital in ensuring that the replication and distribution of DNA in the cell ...
Answer and Explanation: Chromatin is spread out within the nucleus of the cell, but when the cell gets ready to divide the chromatin condenses into forming chromosomes. These structures form the histones, which help to create ...
ChromosomesA morphological sex difference was observed in nuclei of nervous and nonnervous tissues of the timber wolf, black bear, red fox and coyote of the order Carnivora. The pig, a member of the order Artiodactyla, showed sexual dimorphism in neuronal nuclei only; multiple chromatin masses ...
chromatin, chromosomes, and chromatids are present in the nucleus of the cell and are composed of DNA, however, they are uniquely identified as described below: Chromatin vs. Chromosome The major difference between chromatin and chromosomes is that chromatin is composed of DNA and histones that ...

Robert,Feil,and,... - 《American Journal of Human Genetics》 被引量: 89发表: 1997年 INSIGHTS FROM MODEL SYSTEMS Genomic Imprinting: A Chromatin Connection Imprinting represents the difference in function of ho-mologous chromosomes, according to their parental origin. In this review, we consider...
3f). This indicates that although most allele-biased and imprinted genes do not have differential compartment status between alleles, there may be subtle differences in higher-order chromatin structure between homologous chromosomes at allele-biased regions, reflecting their underlying allele biases in ...
This difference in chromatin density could be because plant chromosomes are densely condensed and contain high amounts of DNA per unit length compared with human chromosomes25. Estimations from DNA contents of each chromosome in human17 and barley26 and chromosome photographs of human27,28,29,30,...
1.The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. 2.The first stage of meiosis, constituted by a series of events that include the thickening and coiling of ...
chromosomes 8 and 19 with the genomic location and density estimate plotted on the x- and y-axis, respectively.eChromosomal distribution of SNVs identified on chromosomes 8 and 19 for both WT (blue) and CC16-/- (red) samples. The regions between the dashed lines indicate the SNV hotspots...
