Question

When the mitochondrial RNA Polymerase makes the CO1 mRNA from the CO1 gene,
the mRNA must then be translated into a protein.
Evaluate the underlined part of the sentence as...Circle one: ( TRUE or FALSE )
13. Which enzyme/cell structure
synthesizes new proteins during
translation?
a. DNA polymerase
b. Nucleus
c. Ribosome
d. RNA polymerase
14. This is a cartoon image of a
ribosome in the middle of
making a new protein. Add the
following labels onto the
cartoon to the right:
a. Amino acid
b. Large ribosomal subunit
c. Small ribosomal subunit
d. CO1 mRNA
e. CO1 protein

Answer 1

1. Evaluating the underlined part of the sentence:
**FALSE** - The mRNA must be translated into a protein by the ribosome, not by the mitochondrial RNA Polymerase.

2. Which enzyme/cell structure synthesizes new proteins during translation?
**c. Ribosome**

3. For the cartoon image of the ribosome, I can’t physically label the image, but I can describe where you might typically place the labels:
- **Amino acid**: These would be shown attached to the tRNA at the ribosomal site.
- **Large ribosomal subunit**: This is typically the larger structure in a ribosome diagram, it usually encompasses the peptidyl transferase center.
- **Small ribosomal subunit**: This is typically the smaller component of the ribosome where mRNA binds.
- **CO1 mRNA**: This would be depicted as a strand of nucleotides running through the ribosome, usually at the interface between the large and small subunits.
- **CO1 protein**: This would typically be shown emerging from the ribosome, or at the end of the translation process, indicating the newly synthesized protein.

You would need to place these labels according to a typical diagram of a ribosome translating mRNA into a protein.
