Spinal tumors can cause back pain, weakness, and numbness in the legs and arms, and more serious issues. Cat-scratch disease. Cat scratch disease is a bacterial infection caused by a cat scratch or bite.
rRNA itself is transcribed in the nucleolus, where ribosomes are assembled (from rRNA and ribosomal proteins) in totality. Keep in mind though, that the ribosomal proteins are translated from mRNA outside the nucleus and imported back in before they can be used for ribosome assembly in the nucleolus.Click to expand...ll RNA is produced in the nucleus. The thing about rRNA is that it is constitutively expressed. The rRNA genes are encoded for multiple times along the length of the genome.
It stands for Ribosomal. So in particular, rRNA is ribosomal RNA and all that means is that it's the RNA that is a part of the ribosomes. To understand what rRNA does, you have to know what ribosomes do and how they interact with the tRNA and mRNA.Basically, rRNA is what makes up the large and small subunits of a ribosome, which is responsible for making proteins out of information sent from the DNA.NA gets transcribed from the nucleus into mRNA (messenger RNA) that has the code for a protein. This code then runs through the ribosome where it meets with it's complementary tRNA (transfer RNA) bases and is translated into proteins.
