The proteins are expressed differently in each cell.
Different cell types show differential gene expression (controlled by transcription factors and epigenetic marks), so the same DNA yields different sets of proteins. Cells do not discard DNA, tRNA sequences are not cell‑specific in that way, and cells do not normally mutate during transcription.
