Question

procedure
place the steps of protein synthesis in the correct order by numbering them 1 - 6 in the blanks:
____ dna rejoins and mrna leaves the nucleus
____ the mrna codons pair up with the trna anticodons; amino acids are added
____ dna unzips
____ a mrna copy of the dna is made
____ amino acids continue to be added until \stop\ is reached.
____ mrna enters the ribosomes
directions
use the dna nitrogen bases below to determine the correct mrna and trna sequence and the correct amino acids.

Explanation:

Protein synthesis involves two main processes: transcription (in the nucleus) and translation (in the ribosomes). First, DNA unzips (transcription initiation). Then, a mRNA copy of the DNA is made (transcription). After that, DNA rejoins and mRNA leaves the nucleus (end of transcription). mRNA then enters the ribosomes (translation initiation). Next, the mRNA codons pair up with the tRNA anticodons; amino acids are added (translation elongation). Finally, amino acids continue to be added until a "stop" codon is reached (translation termination).

Answer:

DNA unzips - 1
a mRNA copy of the DNA is made - 2
DNA rejoins and mRNA leaves the nucleus - 3
mRNA enters the ribosomes - 4
the mRNA codons pair up with the tRNA anticodons; amino acids are added - 5
amino acids continue to be added until "stop" is reached - 6
