Transcription is a process of making an RNA strand from a DNA template, and the RNA molecule that is made is called transcript. In the synthesis of proteins, there are actually three types of RNA that participate and play different roles: a.
The closed MRI system allows for finer resolution than the open MRI system. Due to the technology used, a closed MRI is able to capture the insides of the human organism with the finest precision. Specialists can have a clearer picture of the object and the resulting diagnosis is therefore more precise.
There are three different types of open MRI machine constructions: Semi open high field MRI scanners provide an ultra short bore (tunnel) and widely flared ends. In this type of MRI systems, patients lie with the head in the space outside the bore, if for example the hips are examined. See an example of a semi-open high field MRI scanner here. Open low field MRI machines have often a wide open design, e.g. an open C-arm scanner is shaped like two large discs separated by a large pillar. Patients have an open sided feeling and more space around them allows a wider range of positions.
