Question

Label the steps for protein synthesis in order, beginning with the first step.


_________ Once the protein is made, the gene for a particular trait is expressed.


_________ mRNA joins the ribosome, and the anticodons from tRNA join mRNA to form a chain of amino acids.


___________ RNA polymerase unzips DNA and free RNA nucleotides join DNA to form mRNA.


__________ A chain of amino acids is formed from peptide bonds, creating a protein.


__________ mRNA is transported from the nucleus of the cell to the ribosomes of the cell.

Answer 1

Answer:

Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can “read” the bases in one of the DNA strands. The enzyme is ready to make a strand of mRNA with a complementary sequence of bases.

Elongation is the addition of nucleotides to the mRNA strand.

Termination is the ending of transcription. The mRNA strand is complete, and it detaches from DNA
