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 tRNA (transfer RNA) - Type of RNA that delivers amino acids to ribosomes during translation in the order specified by the mRNA. 2  rRNA (ribosomal RNA) - A type of RNA that becomes part of ribosomes.here are different types of RNA, ribosomal RNA, messenger RNA and transfer RNA. Ribosomal RNA (rRNA) is found in ribosomes and in the nucleolus where it is manufactured. messenger RNA (mRNA) can be found in the nucleus when it is translating DNA to mRNA in translation.
