-
transcription
An enzyme attaches to the DNA molecule at the gene of interest. -
transcription
The two strands of DNA separate at that location. -
transcription
Complementary RNA nucleotides bond to the nitrogenous bases on one of the separated DNA strands. -
transcipition
The chain of RNA nucleotides forms a single-stranded molecule of RNA by using the DNA strand as a template. -
transcription
The chain of RNA nucleotides forms a single-stranded molecule of RNA by using the DNA strand as a template. -
transription
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 -
transcription
The two DNA strands rejoin. -
tranlation
The mRNA attaches to a ribosome, which contains proteins and ribosomal RNA (rRNA). -
translation
Another type of RNA, transfer RNA (tRNA), brings amino acids to the ribosome in the order specified by the codon sequence on the mRNA. -
translation
The anticodon of the tRNA, with its attached amino acid, pairs to the codon of the mRNA, which is attached to a ribosome. -
translation
When a second tRNA with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first tRNA and is bonded to the amino acid of the second tRNA. -
translation
The ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. -
translation
The empty tRNA moves off and picks up another matching amino acid from the cytoplasm in the cell. -
tranlation
This sequence is repeated until the ribosome reaches a stop codon on the mRNA, which signals the end of protein synthesis.
