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.

TRANSCRIPTION

1. Helicase unzips the DNA

2. RNA Polymerase triggers the production of mRNA matching the unzipped      DNA strands

3. mRNA matches A with U and C with G

4. The end of a gene has a series of bases that signal the mRNA to stop copying

5. mRNA is released into the cytoplasm via nuclear pores

TRANSLATION

1. mRNA attached to a ribosome

2. The ribosome then moves along mRNA, reading three bases at a time (codons)

3. For each mRNA codon read by the ribosome, a tRNA anticodon with bring an amino acid

4. tRNA leaves behind the amino acid and can pick up more from the cytosol

5. Peptide bonds join the amino acids left by the tRNA, each peptide bond requires 1 ATP molecule

6. A chain of amino acids forms a protein

a community that experiences major changes undergoes progress

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
