amino acid chains are assembled from information in the mRNA.

|
Free floating amino acids are picked up by tRNA.

Detailed explanation-1: -The large subunit of the ribosome has three sites at which tRNA molecules can bind. The A (amino acid) site is the location at which the aminoacyl-tRNA anticodon base pairs up with the mRNA codon, ensuring that correct amino acid is added to the growing polypeptide chain.
Detailed explanation-2: -Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.
Detailed explanation-3: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
Detailed explanation-4: -mRNA Function Each piece of mRNA encodes the information for one protein in eukaryotes (or more than one protein in prokaryotes). During translation, ribosomes use the instructions conveyed by mRNA as a template for recruiting and assembling the amino acids to create the desired peptides/protein.
Detailed explanation-5: -The process of amino acid assembly takes place in the ribosome. This structure consists of two subunits containing ribosomal RNA that enclose the mRNA, and catalyze the formation of the amide linkages in the growing protein in a process known as translation.
