These are transcribed in the nucleolus by RNA polymerase I. 45S is processed in the nucleus via 32S rRNA to 28S [6] and 5.8S, [7] and via 30S to 18S, [8] as shown in the diagram. 18S is a component of the ribosomal 40S subunit. 28S, 5.8S and 5S, [9] which is transcribed independently, are components

The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to ...
DNA repair defects are seen in nearly all of the diseases described as accelerated aging disease, in which various tissues, organs or systems of the human body age prematurely. Because the accelerated aging diseases display different aspects of aging, but never every aspect, they are often called segmental progerias by biogerontologists .
Diagram of the nucleus showing the ribosome-studded outer nuclear membrane, nuclear pores, DNA (complexed as chromatin), and the nucleolus. The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments called the nuclear matrix, and is enveloped in a double membrane called the nuclear envelope.
It is generally caused by damage to the subthalamic nucleus (STN). Since the internal segment of the globus pallidus (GPi) is the link in the circuit between the STN and thalamic projection, destruction of localized brain cells in the GPi via a pallidotomy has proven to serve as a useful treatment for hemiballismus.
Giant cell arteritis, [6] also known as temporal arteritis or cranial arteritis, is the most common MGC-linked disease. This type of arteritis causes the arteries in the head, neck, and arm area to swell to abnormal sizes. Although the cause of this disease is not currently known, it appears to be related to polymyalgia rheumatica. [7]
In medicine, proteinopathy ([pref. protein]; -pathy [suff. disease]; proteinopathies pl.; proteinopathic adj), or proteopathy, protein conformational disorder, or protein misfolding disease, is a class of diseases in which certain proteins become structurally abnormal, and thereby disrupt the function of cells, tissues and organs of the body.
