Chapter 6: Molecular Genetics Test Exam
Questions with Correct Answers
1. Central Dogma of Molecular Biology correct answers: information is transferred from
DNA to RNA to proteins, but once the information is in the form of a protein, the transfer cannot be
reversed.
2. DNA Replication correct answers: the process of copying a strand of DNA.
3. from protein to RNA, because a protein cannot go back to being RNA.
correct answers: According to the central dogma of molecular biology, which transfer of of
information is NOT possible?
4. To ensure that daughter cells have a complete copy of DNA correct
answers: What is the primary purpose of DNA replication?
5. CGAAGT correct answers: What would be the DNA complement to GCTTCA?
6. Anticodon correct answers: the sequence of nucleotides on transfer RNA that pairs with the
codons of messenger RNA.
7. Codon correct answers: a sequence of three nucleotide bases that represents the code for one
amino acid.
8. Messenger RNA (mRNA) correct answers: a type of RNA that transfers the code from DNA in
the nucleus to the cytoplasm.
9. Peptide bond correct answers: the bond between each amino acid in a protein.
10. Ribosomal RNA (rRNA) correct answers: a type of RNA that "reads" the codons from
the messenger RNA.
11. Ribonucleic Acid (RNA) correct answers: a single strand of nucleotides; ditterent types
are used to translate instructions from DNA into making proteins.
12. RNA polymerase correct answers: the enzyme responsible for creating RNA from a
DNA template.
13. Stop Codon correct answers: a sequence of three nucleotide bases that indicates the end of
protein synthesis.
14. Transcription correct answers: the process occurring in the nucleus of a cell that copies
the instructions from a part of DNA onto a strand of messenger RNA.

, 15. Transfer RNA (tRNA) correct answers: a type of RNA that carries an amino acid and
transfers it to the protein chain being assembled in the ribosome.
16. Translation correct answers: the process occurring in the cytoplasm of a cell that build
proteins.
17. DNA>mRNA>amino acid>protein correct answers: The correct sequence of
protein synthesis in a cell.
18. It copies the instructions in DNA onto a strand of mRNA.
correct answers: What is the role of transcription in protein synthesis?
19. messenger RNA correct answers: Which molecule carries the genetic code from the
nucleus of a cell to a ribosome in the cytoplasm?
20. a sequence of three bases that codes for an amino acid correct
answers: Which of the following BEST describes a codon?
