In dna, only the_ varies from one nucleotide to another. base phosphate sugar amino acid

I’m doing some practice exam questions for biology, and i’m not sure how to do these 3 parts to the question.

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell
