-
An enzyme attaches to the DNA molecule at the gene of interest
-
The two strands of DNA separate at that location.
-
Complementary RNA nucleotides bond to the nitrogenous bases on one of the separated DNA strands.
-
The chain of RNA nucleotides forms a single-stranded molecule of RNA by using the DNA strand as a template.
-
When a stop codon is reached, the RNA strand separates from the DNA molecule, leaves the nucleus and goes through the nuclear membrane into the cytoplasm.
-
The two DNA strands rejoin
-
The mRNA attaches to a ribosome, which contains proteins and ribosomal RNA (rRNA). The function of ribosomes is to assemble proteins according to the genetic message.
-
Another type of RNA, transfer RNA (tRNA), brings amino acids to the ribosome in the order specified by the codon sequence on the mRNA. At one end of each tRNA is the anticodon.
