What type of organelles do prokaryotes have, if any? What organelle is responsible for protein synthesis? What does chromatin do? What is a cell as stipulated in biology? What are the organelles of a plant cell? What is the cytoskeleton made up of?
What is the phase where chromatin condenses to form chromosomes? What part of a cell contains chromosomes? Do plant cells have DNA? In what part of a cell would you find most of a cell's genetic material? What are the organelles involved in protein synthesis and the functions of these or...
Wolffe AP, Khochbin S, Dimitrov S (1997) What do linker histones do in chromatin? Bioessays 19:249–255Wolffe AP, Khochbin S, Dimitrov S (1997) What do linker histones do in c...
DNA in cells exists in the form of chromatin, which is a long, linear substance consisting of about one-third DNA and two-thirds protein molecules called histones. These proteins serve the vital function of compelling DNA to coil and twist in on itself to such a remarkable extent that a si...
Chromatid Formation Chromatids are produced fromchromatinfibers during both meiosis and mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA...
A. Alodine is a trade name for a brand of chromating solution used for MIL-C-5541 conversion coating of aluminum. Iridite is another trade name. The conversion coating can be done in clear, yellow, or yellow-and-leach (leach back to clear). Normally, the conversion coating is either for...
Here, the strands of DNA are found around proteins known as histones to form nucleosomes that coil to form chromatins. In some cases, however, the DNA is wound around non-histone chromosomal proteins. Based on molecular studies, researchers have shown that each of the nucleosomes consists ...
Chromatin-immunoprecipitation and sequencing analysis confirmed that Olig2 directly targets the promoter and/or enhancer regions of Nfatc4, Dscr1/Rcan1 and Dyrk1a, the critical neurogenic genes that contribute to Down syndrome phenotypes and inhibit their expression. Another study by Chakrabarti et al...
Ubiquitin proteasome system (UPS): what canchromatin do for you?Brenda C O’Connell and J Wade HarperCul4–Ddb1, a RING H2 ubiquitin ligase, plays an important rolein many vital cellular processes including DNA replication, DNArepair and transcription. Recent research reveals strong linksbetween ...
