Lesson details
Lesson outcome
I can describe how cells use the instructions coded in DNA to assemble proteins.
Show transcript
The sequence of nucleotides in a gene is a template for assembling proteins from amino acids in a particular order.
To make a protein, a copy of a gene is made to form messenger RNA (mRNA) in the nucleus.
The mRNA leaves the nucleus and moves to a ribosome in the cytoplasm.
Transfer molecules (tRNA) carry specific amino acids to the ribosome.
The ribosome joins amino acids in an order determined by the sequence of triplet codes in the mRNA.
