Why amino acids brought to the cellular site

Question

Why amino acids brought to the cellular site where translation occurs? Also state anticodon?

Answer 1

Amino acids are brought to ribosome by RNA molecules termed as transfer RNA, or tRNA. One tRNA related to its vague amino acid joins by a special sequence of three nucleotides to mRNA codon exposed in ribosome. This series in the tRNA is termed as anticodon. The tRNA anticodon should be complementary to the mRNA codon to which it joins, according to the rule A-U, CG. The ribosome then slides all along the mRNA molecule (a procedure termed as translocation) to expose the following codon to the binding of another tRNA. Whenever amino acids corresponding to neighboring codons join by peptide bond the first tRNa is released.
