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 is a copy of the code in the DNA. rRNA is ribosomal RNA. Ribosomes are made of proteins and various RNAs. Any RNA that helps to make a ribosome is called rRNA. tRNA (t = transfer) functions during translation. You need it to turn the mRNA code into a functional protein, which is done on the ribosome.o read the mRNA, ribosomes are used and these are made of rRNA (ribosomal RNA) which form subunits to give the ribosome. The last RNA is tRNA (transfer RNA) which brings the correct amino acid to the ribosome and mRNA complex and add it to the growing polypeptide chain which would eventually form the protein.
