WebbSteps of Protein Synthesis. There are two main steps to protein synthesis: transcription and translation. Transcription is when mRNA is created from DNA in the nucleus of the cell. Once created, translation occurs when the mRNA is interpreted into amino acid chains by a ribosome. These amino acid chains form proteins. WebbThe large subunit attaches and the initiator tRNA, which carries methionine (Met), binds to the P site on the ribosome. Figure 12.6.1: Translation begins with when tRNA anticodon recognizes a codon on the mRNA.

Webb22 juni 2024 · RNA is a lot like DNA—it’s got a sugar-phosphate backbone and contains sequences of nitrogenous bases. However, there are a couple of vital differences between RNA and DNA: RNA has only one nucleotide chain. It looks like only one side of the DNA ladder. RNA has ribose as the sugar in its backbone.
