WebTranslation initiation is a key step for regulating the synthesis of several proteins. In bacteria, translation initiation involves the interaction of the mRNA with the ribosomal small subunit. Additionally, translation initiation factors 1, 2, and 3, and the initiator tRNA, also assemble on the ribosomal small subunit and are essential for ... WebTranslation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain. Image credit: " …

At the initiation of translation ribosomes and tRNA bind to the mRNA. tRNA is located at the first docking site of the ribosome.The anticodon of this tRNA is complementary to the start codon of the mRNA where translation begins. After binding to the mRNA, the ribosome …

WebTranscription is initiated by the attachment of a protein known as a sigma. The sigma attaches to one strand of the DNA (the template strand) at a very specific location. In bacteria, several sigmas exists and each one initiates the transcription of a specific sequence of DNA (or gene). WebTranslation is the process by which protein is synthesized by ribosomes from the genetic information carried in a molecule of messenger RNA (mRNA). Translation occurs in three phases - Initiation, Elongation, and Termination. mRNA carries genetic information in the form of the codon, which is a set of three nucleotides (triplet).
