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.
Internet-Based Tools for Teaching Transcription and Translation Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Here is a more complete definition of transcription: Transcription Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
