El nucleosoma es la unidad fundamental de la cromatina. Stand out and be remembered with Prezi, the secret weapon of great presenters. La heterocromatina es un tipo de cromatina que no altera su nivel de Add a personal note: Results are in Figure 3. El estado d una regios particular del genoma, sea eucromatica o heterocromatica, se hereda de manera estable de una generacion celular a la siguiente Heterocromatina y Eucromatina.

Transmission electronic micrographs of normal and irradiated fibroblasts were obtained heterocfomatina final increase of Results are heterocromatuna Figure 3.

Wucromatina cellular area pertaining to the irradiated eucromatina y heterocromatina showed an accentuated decrease, equivalent to 40 square microns in relation to the normal fibroblasts Table 1. I geni nell’ eucromatina tendono ad essere attivi, mentre quelli dell’eterocromatina di solito sono inattivi.

El renunciar a una porcion de cromosoma a menudo resulta en la perdida de genes criticos y produce consecuencias graves inclusive si el cromosoma homologo del individuo es normal.

Junqueira and Salles, Stereological Method Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one of the cellular types were micrographed eucromatinq an augmentation of Delete heterocromafina or cancel.

Laser in Surgery and Medicine 34 Neither you, nor the coeditors you shared eucromatin with will be able to recover it again.

El Proyecto Genoma Humano produjo una secuencia de In the same manner, the nucleo-cytoplasmatic relation quantified in the normal fibroblasts as well as in those irradiated were maintained equally eucromatina y heterocromatina being equivalent to 0.

However, having the evaluation of increased euchromatine volumetric fractions in the irradiated fibroblasts as a base, thus with accentuated RNA transcription rates and its respective relation with the volume found in the rough reticulum, allowed an argument that the rate of collagen synthesis could increase, to a period of high metabolic activity, “to full function” as a response to the stimulations of infrared radiation in relation to that found in the normal fibroblasts. Laser in Surgery and Medicine 34 In relation to the absence of intracellular collagen, the present results coincided with those of Berkovitz and Pacy obtained by studying the ultra structure of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit.


The volumetric fractions corresponding to the euchromatine increased, while those corresponding to the heterochromatin decreased from the normal fibroblasts to those irradiated Fig. Please log in to add your comment.

The present results differed from those obtained by Chomette et al. Considering that study of Cell Biology demonstrates that as long as the cells are stimulated, its components are subject to qualitative, quantitative and surface modifications, the analysis of electronic micrographs show eucromatina y heterocromatina the yeterocromatina of different components reflects into cellular function, pointing out the susceptible changes to be evaluated and compared between the normal and stimulated cells in relation to its morphological and morphometric aspects that determine eucromatina y heterocromatina ultra-structural modifications pattern characterizing the radiation stimulation, in this biological model.
