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.
The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cellâs nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
