Is an autosomal cell a somatic cell? Are autosomal genes on the same chromosome? Do autosomal cells have chromosomes? Do all somatic cells have the same amount of DNA? Do different somatic cells have the same DNA? Are gametes cells genetically identical to somatic cells?
of both the biochemical and molecular processes is important for understanding the mechanisms by which a single somatic cell becomes a whole plant. Modern... AS Heringer,C Santa-Catarina,V Silveira - 《Proteomics》 被引量: 2发表: 2018年 加载更多来源...
A mechanism of aging is proposed for mammals and other vertebrates. In this mechanism, most somatic cells have inherent deficiencies in methylation metabolism with respect to their capacity to methylate DNA. This leads to incomplete DNA methylation in each cell cycle which, accumulated over many cell...

The mitotic spindle has a crucial role in ensuring the accurate segregation of chromosomes into the two daughter cells during cell division, which is paramount for maintaining genome integrity. It is a self-organized and dynamic macromolecular structure that is constructed from microtubules, microtubule...
Communication between the soma and germline optimizes germ cell fate programs. Notch receptors are key determinants of germ cell fate but how somatic signals direct Notch-dependent germ cell behavior is undefined. Here we demonstrate that SDN-1 (syndecan
Female sheep B provides a somatic cell for the clone. The nucleus of this cell contains all the genes needed to produce a new sheep.
Since only one of the two X-chromosomes is active in XX somatic cells, a woman who is heterozygous at this locus for the common gene, GdB (which determines B-type G6PD) and a variant allele such as GdA (which determines type A enzyme) has two distinct cell populations, one producing B...
Similar to our CNV analysis, transcriptional clustering revealed that the malignant cell compartment of Vκ*MYC mice is comprised of multiple molecular subpopulations per mouse (3–13 transcriptional clusters, Fig. 3b). The fact that samples with a similar number of cells did not have the same ...
From the perspective of cell composition, scRNA-seq datasets are always imbalanced, which have common cell types and rare cell types. The rare population is a small proportion of cells in the single-cell dataset. For example, the dendritic cell usually takes 1–5% of peripheral blood ...
