A crucial structure within the nucleus is the nucleolus, a dense, non-membrane-bound region responsible for ribosomal RNA (rRNA) synthesis and ribosome biogenesis. Ribosomes, the protein synthesis machinery of the cell, are assembled in the nucleolus before being exported to the ...
Define nucleonics. nucleonics synonyms, nucleonics pronunciation, nucleonics translation, English dictionary definition of nucleonics. n. 1. The study of the behavior and characteristics of nucleons or atomic nuclei. 2. Development of instruments for use
The nucleolus is a cellular structure found in the nucleus of eukaryotic cells. Some cells have several nucleoli, which work as a...
The nucleolus is the site within the eukaryotic nucleus of transcription of rDNA, of processing of the rDNA transcripts, and of the formation of pre-ribosomal particles. We review current ideas for the molecular organization of these processes. The earliest transcriptional events take place near the...
nucleole, nucleolus - a small round body of protein in a cell nucleus; such organelles contain RNA and are involved in protein synthesis chromatin, chromatin granule - the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it co...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
The nucleus is a spherical or oval organelle which contains the genetic material of a eukaryotic cell. It is often the largest organelle within an animal cell, as seen in Figure 4 below, and it is often stained when observed with a light microscope which makes it easy to identify in a ph...
Nucleolus the dense light-refracting body within the cell nucleus of eukaryotes. The nucleolus consists mainly of ribo-nucleoproteins, that is, proteins that contain ribonucleic acid (RNA). Usually there are one to three nucleoli in a nucleus. In a few organisms (amoebas, testaceans) and in...
