Cervical stenosis is a narrowing of the spinal canal which protects the spinal cord.atients who present with symptoms suggestive of cervical stenosis are usually worked up with a neurological evaluation and a CT scan or MRI scan. An MRI scan is particularly good at evaluating the spinal canal, the spinal cord and the nerves coming and going from the spine.
The ribosome itself is highly complex. It is made up of dozens of distinct proteins (the exact number varies a little bit between species) as well as a few specialized RNA molecules known as ribosomal RNA (rRNA). Note â these rRNAs do not carry instructions to make specific proteins like mRNAs.
Protein synthesis is where RNA comes into a ribosome after copying DNA. There, the RNA's copy gets transformed into a protein when the specific order of amino acids is read. So, in short, ribosomes make all of the cell's proteins, which are needed to do everything in the cell. Ribosomes are first made in the nucleus, but they can be found on the Rough Endoplasmic Reticulum (Rough ER) and freely floating around in the cell's cytoplasm. Ribosomes work with every organelle in the cell due to their making of proteins, which are needed to build everything.
