Exemples d’utilisation de CHROMATIN dans une phrase

• These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, DNA fragmentation, and mRNA decay.
• During mitosis and meiosis, chromatin facilitates proper segregation of the chromosomes in anaphase; the characteristic shapes of chromosomes visible during this stage are the result of DNA being coiled into highly condensed chromatin.
• Arrow points to sex chromatin in DAPI-stained cell nucleus, and to the corresponding sex chromatin site in the histone macroH2A1-staining.
• Euchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription.
• The main occurrences in prophase are the condensation of the chromatin reticulum and the disappearance of the nucleolus.
• Chromosomes are linear arrangements of condensed deoxyribonucleic acid (DNA) and histone proteins, which form a complex called chromatin.
• As chromosomes reach the cell poles, a nuclear envelope is re-assembled around each set of chromatids, the nucleoli reappear, and chromosomes begin to decondense back into the expanded chromatin that is present during interphase.
• During this time period, investigations of rat liver nuclei revealed that lamins have an architectural relationship with chromatin and nuclear pores.
• In eukaryotes, the accessibility of large regions of DNA can depend on its chromatin structure, which can be altered as a result of histone modifications directed by DNA methylation, ncRNA, or DNA-binding protein.
• This motif facilitates the formation of heterodimers, which subsequently assemble into a histone octamer, playing a crucial role in the packaging of DNA into nucleosomes within chromatin.
• Karyorrhexis (from Greek κάρυον karyon 'kernel, seed, nucleus' and ῥῆξις rhexis 'bursting') is the destructive fragmentation of the nucleus of a dying cell whereby its chromatin is distributed irregularly throughout the cytoplasm.
• Pyknosis, or karyopyknosis, is the irreversible condensation of chromatin in the nucleus of a cell undergoing necrosis or apoptosis.
• Chromatin structure remodeling (RSC) complex, a 17-subunit complex with the capacity to remodel the structure of chromatin.
• Lymphoblasts can be distinguished microscopically from myeloblasts by having less distinct nucleoli, more condensed chromatin, and an absence of cytoplasmic granules.
• With the use of aniline dyes he was able to find a structure which strongly absorbed basophilic dyes, which he named chromatin.
• Endolimax nana nuclei have a large endosome somewhat off-center and small amounts of visible chromatin or none at all.
• 5-methylcytosine residues are excised and replaced with unmethylated cytosines allowing access to the chromatin structure of the enzymes and proteins necessary for transcription and subsequent translation.
• As a graduate student with Ira Herskowitz Rine codiscovered yeast SIR proteins, conserved chromatin organizing proteins that modulate gene expression across taxa.
• In dying cells, DNA is cleaved by an endonuclease that fragments the chromatin into nucleosomal units, which are multiples of about 180-bp oligomers and appear as a DNA ladder when run on an agarose gel.
• The nuclear matrix proteome consists of structural proteins, chaperones, DNA/RNA-binding proteins, chromatin remodeling and transcription factors.
