In this lesson, learn what the nucleus is and where it is located inside plant and animal cells. Understand the anatomy of a nucleus and its...
A Drosophila rRNA gene located in euchromatin is active in transcription and nucleolus formation. P-element transformants of a single rRNA gene (rDNA) were used to investigate the relationship between the organization of the nucleolus organizer (NO) and rDNA function in Drosophila melanogaster. In ...
(a) Where in the cell is DNA found? (b) Why is DNA not the actual working molecule of the cell? Explain the following term: Prokaryotic DNA. a. Is DNA found in all living organisms? b. Where in the cell is the DNA located? c. What is the function of DNA?
RNA–chromatin interactomechromatinepigeneticstranscriptionIt was noticed in the early 1960s that a large amount of RNAs is associated with chromatin. What kind of RNAs are they? Where are they located on chromatin? When and in what processes do these RNAs perform their physiologically normal or ...
Where are proteins made in the eukaryotic cells? A. Golgi apparatus B. Ribosome C. Nucleus D. Cell wall E. Plasma membrane What is the definition of Ribosomes? Give at least 4 examples, and facts/characteristics. Where is tRNA located in the cell? Where is ribosomal RNA produced? Where ...
In higher organisms, this hormone is rhythmically secreted by the pineal gland and it has been adopted as a darkness molecule [2] due to its higher plasma concentrations during the night and its acute suppression by light at night (LAN). However, apart from the central...

Sp7/Osterix is a key transcriptional determinant of bone-secreting osteoblasts. We performed Sp7 chromatin immunoprecipitation sequencing analysis identifying a large set of predicted osteoblast enhancers and validated a subset of these in cell culture and transgenic mouse assays. Sp family members bind ...
This observation was summarized in the deterministic replicon model, which was proposed nearly 50 years ago and is still the dominating model of the control of DNA replication during the cell cycle. Jacob et al. suggested that a genetically defined cis-element, termed replicator, interacts with a...
pheochromocytomas are equally hard to treat. Thus, the challenge for the next 10 years is to translate the important discoveries of the previous decade into substantial advances in the treatment of adrenal disorders and tumors. Introduction Adrenal endocrinology has always stood at the forefront of ...
