4.2.8 Protein synthesis review worksheet:

1. Complete the table below to contrast the structure of DNA and RNA.

2.Describe the role of each type of RNA in a cell:

mRNA:

 tRNA:

ribosomal RNA:

3.Fill in the blanks to complete the sentences.

a The process where mRNA is used to make proteins in the ribosomes is called

________________________.

b. In eukaryotes, mRNA is formed in the _______________ and then travels to the

____________________. 

c. The process of using DNA to produce complementary mRNA molecules is called

_________________________.

d. The enzyme                                   binds to DNA during transcription.

 4. Write out a step by step description of what happens in a cell during transcription;

•Use the following terms: DNA, mRNA, nucleus,RNA polymerase, RNA nucleotides

5. Write out a step by step description of what happens in a cell during translation.

Use the following terms: mRNA, tRNA, Codon, anticodon, ribosome, amino acid, protein

Start with the DNA strand at the bottom and work your way up.

4) Last step: Write the sequence of amino acids in the protein that will be created. Hint: remember to use the codons from the mRNA!

3) Write the anti-codons that would be found on the tRNA

2) Write codons on the mRNA strand that would be transcribed

1) DNA strand
