I'm just a little lost on how to explain translation, where the amino acid forms to make a polypeptide chain? How do i explain it in a way that it makes sense! :(

Translation is when the mRNA moves out to the cytoplasm where it will encounter a ribosome. The ribosome translates the messages then a tRNA carrying an amino acid moves towards the mRNA. The anti-codons on the other side of the tRNA attatches itself to a complemntary codon on the mRNA. A peptide bond is then formed between the new amino acid. The tRNA is then "spliced off" and goes out to carry another amino acid where the process will be repeated until a stop codon is reached. Then the polypeptide will be released to be used by other cells.

Hope this helps :/

Pretty much it. Just note however that ONE codon = 3 nucleotides. And that one ribosome can only accommodate 2 codons at a time. (Picture a factory line)
