Put these statements in order The ribosome reads the sequence of codons in the mRNA and instructs a tRNA
to collect a specific amino acid from the cytoplasm
The mRNA leaves the nucleus and goes to the ribosome
Ribosome links the amino acids together into a polypeptide (protein)
Enzymes split the DNA along the gene that is being transcribed
tRNA molecules bring amino acids to ribosome to build a polypeptide
DNA holds the genetic code to build a protein in the nucleus of the cell
tRNA floats off after delivering amino acid to ribosome
Enzymes link the mRNA nucleotides into one long single strand
