1. If a bacterial infection stopped the production of RNA polymerase, the most likely result would be:
**a. A protein could not be manufactured.**
(RNA polymerase is essential for synthesizing mRNA, which is needed for protein production.)
3. The component of the DNA molecule that provides instructions for the production of proteins is:
**c. The sequence of nitrogen bases.**
(The sequence of nitrogen bases in DNA encodes the information required to synthesize proteins.)
4. If the template of a strand of DNA is AGATGCATCS, the complementary strand (assuming "C" is a mistake and should be "A") would be:
**b. CTACGTAGA.**
(The complementary pairs are A-T and G-C. The corrected template strand AGATGCAT would pair with TCTACGTA.)
6. The molecule paired with its correct role in protein synthesis is:
**d. tRNA-transfers amino acids.**
(tRNA's role is to carry amino acids to the ribosome during translation.)
7. The cellular function represented by the model (if referring to multiple components including DNA, RNA, and ribosomes) is likely:
**c. Protein Synthesis.**
(This process involves transcription and translation, where DNA is used to synthesize proteins through RNA intermediates.)
**a. A protein could not be manufactured.**
(RNA polymerase is essential for synthesizing mRNA, which is needed for protein production.)
