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.
1 rRNA is located in the cytoplasm of a cell, where ribosomes are found. 2  rRNA directs the translation of mRNA into proteins. 3  tRNA or Transfer RNA. 4  Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis.nswer: There are actually several types of ribonucleic acid or RNA, but most RNA falls into one of three categories: 1  mRNA or Messenger RNA. 2  mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. 3  mRNA carries genetic information from the nucleus to the cytoplasm of a cell.
