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.

It binds to a messenger ribonucleic acid (mRNA) and reads the information contained in the nucleotide sequence of the mRNA.Transfer RNAs (tRNAs) containing amino acids enter the ribosome in a special pocket, or binding site, called the acceptor site (A site).Once correctly bound, the ribosome can add the amino acid on the tRNA to the growing protein chain.tructure. The ribosome is made up of two parts, called subunits. The larger of the two subunits is where the amino acids get added to the growing protein chain. The small subunit is where the mRNA binds and is decoded.
