Until recently, little was known about the mag-. nitudes of the various nonpoint and point sources of. nitrogen. This knowledge gap has made it difficult to. develop a national strategy for nonpoint-source pollu-. tion prevention and control. Many of the water-pollution-control measures.
Even though the ribosomes are usually considered accurate and processive machines, the translation process is subject to errors that can lead either to the synthesis of erroneous proteins or to the premature abandonment of translation.
  Transcription is the rewriting of the DNA into mRNA, which occurs on the DNA coils in the nucleus (but not the nucleolus). Translation is the process of converting the â¦ mRNA into a protein strand, which occurs on the ribosomes either in the cytoplasm or on the rough endoplasmic reticulum. In eukaryotic cells, transcription occurs in the nucleus from which the transcript it transported to the cytoplasm where translation occurs.     In prokaryotic ce â¦ lls, transcription and translation both take place in the cytoplasm. + 15 others found this useful.
