euchromatin उदाहरण वाक्य

उदाहरण वाक्य

1. After stimulation of the neutrophil response, neutrophils lose their shape, allowing euchromatin and heterochromatin to homogenize, later resulting in the mixing of NET components.
2. Not all euchromatin is necessarily transcribed, but in general that which is not is transformed into heterochromatin to protect the genes while they are not in use.
3. One example of constitutive euchromatin that is'always turned on'is housekeeping genes, which code for the proteins needed for basic functions of cell survival.
4. In general, euchromatin appears as light-colored bands when stained in G banding and observed under an nucleus, possibly as a mechanism to handle increasing genome size.
5. In eukaryotes the structure of chromatin, controlled by the histone code, regulates access to DNA with significant impacts on the expression of genes in euchromatin and heterochromatin areas.
6. These results indicate a decrease in the level of active euchromatin epigenetic marks upon initiation of embryonic stem cell differentiation which is then followed immediately by reprogramming of the epigenome.
7. Euchromatin is the less compact DNA form, and contains genes that are frequently " constitutive " heterochromatin that consists of chromosome structural components such as telomeres and centromeres.
8. Electron microscopic studies in 3 cases described intracytoplasmic mucin, convoluted oval nuclei, prominent nucleoli, homogeneous euchromatin with peripheral chromatin condensation, microvilli, junctional complexes, and primitive lumen formation.
9. Nucleosomes consist of eight proteins known as histones, with approximately 147 base pairs of DNA wound around them; in euchromatin, this wrapping is loose so that the raw DNA may be accessed.
10. It is known that methylation of histones often serve as marks that cause the formation of heterochromatin, an inactive form of chromatin, while acetylation often marks euchromatin, an active form of chromatin.
