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.
The ribosome is a cellular machine found in all organisms. It serves to convert the instructions found in messenger RNA (mRNA, which itself is made from instructions in DNA) into the chains of amino-acids that make up proteins. That is, the ribosome is responsible for the synthesis of proteins. Structure and shape of the E.coli 70S ribosome.
