Question 1
1.

Sort the following into each step:

  • Is the first step of protein synthesis and occurs in the nucleus
  • Involves copying a gene
  • Can either occur in the cytoplasm or the rough ER
  • Involves RNA Polymerase
  • Involves amino acids being bound together
  • Starts at the promoter in DNA
  • Ends at the termination sequence in DNA
  • Involves making peptide bonds
  • Occurs in between transcription and translation
  • The small step that occurs right before the mRNA leaves the nucleus to prepare the mRNA for translation
  • Involves reading mRNA
  • Involves a ribosome making a protein
  • Involves making mRNA
  • Involves tRNA
  • Transcription
  • RNA Processing
  • Translation
Question 2

What is a portion of DNA that codes for/contains the instructions for how to make one protein called?

Question 4
4.

What does RNA Polymerase make?

Question 5
5.

Which of the following is true about mRNA? Select all that apply.

Question 6
6.

During transcription the RNA polymerase binds to the ___________ before a gene.

Question 7
7.

The whole DNA molecule is unzipped by the RNA polymerase during transcription.

Question 8
8.

The RNA polymerase breaks hydrogen bonds.

Question 9
9.

RNA polymerase unzips a small portion of DNA while it copies the gene, and the DNA reanneals as the RNA polymerase moves down.

Question 15
15.

Then the portions of the mRNA that do code for proteins are bound together. These parts of the mRNA are called ...

Question 16
16.

Then two structures are added to the ends of the mRNA to indicate which direction to read it and protect it. Which of the following is added to the mRNA before leaving the nucleus?
