Put the steps of transcription and translation in the order that they occur in.
mRNA connects to the ribosome and translation begins.
The Stop codon is reached and mRNA leaves the nucleus with the copied strand of DNA.
Codons on the mRNA pair up with anti-codons on the tRNA, which brings in the correct amino acids.
RNA nucleotides match their bases to the bases on one of the DNA strands and a strand of mRNA is made.
Amino acids are added together with peptide bonds to make a protein. Translation is complete.
Transcription begins when DNA is "unzipped" beginning at a start codon.
