Lead poisoning causes sudden pain on either side of the lower back, urinary issues, nausea, fever, and chills. Spinal tumor. 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.
This brief animation demonstrates the process by which messenger RNA (mRNA) is translated into protein. RNA is present in several formsâmessenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each of these RNA forms is involved in different steps of protein synthesis.mRNA is generated from DNA and is the template for protein synthesis. tRNA is critical to the translation of the mRNA sequence into protein sequence. rRNA are components of the ribosomes, which are the sites of protein synthesis.RNA is generated from DNA and is the template for protein synthesis. tRNA is critical to the translation of the mRNA sequence into protein sequence. rRNA are components of the ribosomes, which are the sites of protein synthesis.
