During protein synthesis ribosomes translate
WebProtein synthesis consists of two stages – transcription and translation. In transcription the DNA code is read, and in translation the code is used to build up protein molecules. … WebAt the beginning of translation, the ribosome and a tRNA attach to the mRNA. The tRNA is located in the ribosome’s first docking site. 6 ... stop codon – a three-nucleotide sequence that signals the cell to end protein synthesis during translation transcription – the process in which a cell’s DNA is copied into messenger RNA, which is then
