Detailed explanation-1: -How does the presence of tRNA in ribosomes allow ribosomes to manufacture proteins? It allows sequencing of amino acids based on an mRNA template. It allows for random distribution of amino acids. It stores chemical energy required for manufacturing proteins.
Detailed explanation-2: -Ribosomes provide a structure in which translation can take place. They also catalyze the reaction that links amino acids to make a new protein. tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.
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 carries information from DNA that are required in protein synthesis. tRNA is an adaptor molecule which carries amino acids for translation. Ribosome provides the site for protein synthesis as well as suitable enzymes which are helpful in translation process.
