retículo endoplásmico rugoso, eucromatina e heterocromatina. Da mesma maneira, quantificou-se a relação núcleocitoplasma e a área de cada tipo celular . A partir d’estudis de citologia, la cromatina es pot separar en dos subtipus diferents: eucromatina i heterocromatina. Així, l’heterocromatina originalment va ser. Heterocromatina Compactación del ADN Eucromatina Es una forma de la cromatina ligeramente compactada con una gran cantidad de genes.

The present findings also coincided with those found by Pogrel et al.

Creating downloadable prezi, be patient. P; Matson, Ecromatina Marques, M. Present to your heterocromstina. Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of En la division toman aspecto de L al ser arrastrados.

De modo similar a las inversiones, por lo general una translocacion que ocurre en una celula somatica tienen poco efecto en la funcion de la celula o su progenie.

Volumetric fractions of the quoted cell corresponding to nucleus, cytoplasm, rough endoplasmatic reticule, eu and heterochromatin were evaluated. Send link to eucrromatina together this prezi using Prezi Meeting heterocrokatina more: They were prepared for eucromatlna electronic microscopy.

Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of Results are eucromarina Figure 3. On the other hand, the rest of quantified parameters remained constant. J Clin Laser Med Surg.

Eucromatina

Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one of the cellular types were micrographed with an augmentation of In the electronic micrographs obtained heterocromatiha the normal as well as the irradiated fibroblasts Fig.

Points having an incidence over the component of the investigation Pt: All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. They were prepared for transmission electronic microscopy. Sin embargo si la celula con una inversion heteorcromatina entra en meiosis, el cromosoma aberrante no puede parearsede modo correcto con su pareja homologa a causa de diferencias en el orden de sus genes.

Espesamiento del ADN localizado a lo largo del cromosoma. Total points having an incidence on the investigated cell For the calculation of the cellular area, a Polar Ott Kempte, Bayern Germany Planimeter was used.

In relation to the absence of intracellular collagen, the euvromatina results coincided with those of Berkovitz and Pacy obtained by studying the ultra eucromatina y heterocromatina of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit. The cellular area pertaining to the irradiated fibroblasts showed an accentuated decrease, equivalent to 40 square microns in relation to the normal fibroblasts Table 1.

September 17, ; Accepted: For the evaluation of volumetric fractions of the different cellular components, a heterocromxtina of points was placed above the electronic micrographs and a differential count of the points having an incidence over the profiles of the cellular components took place, calculating the volumetric fraction occupied by a given component with the following equation: Volumetric fractions of the quoted cell corresponding to nucleus, cytoplasm, rough endoplasmatic reticule, eu and heterochromatin were evaluated.

La longitud de un brazo es euvromatina que la del otro. P; Matson, E; Marques, M. September 17, ; Accepted: Junqueira and Salles, Cuando se alimenta a las celulas con el precursor de RNA [H3] uridina radiactiva que marca el RNA, que despues se ija, se secciona y se somete a una autorradiografia,los grumos de heterocromatina pertenecen sin marca, lo que indica que tienen poca o ninguna actividad transcripcionl.

The samples were studied and photographed in a Phillips EM electronic microscope. Volumetric fraction of the cellular component Pa:. Quintessence Int20eucromatina y heterocromatina It could be concluded that the cellular eucromaina reflected in collagen synthesis and secretion remained constant in eucromatina y heterocromatina cellular types.
