Questions MOLECULAR
with Correct Answers
1. Where are the beta-carotene genes found in daffodils?
correct answers: NUCLEUS Dattodils are eukaryotes, so their DNA is
found in the nucleus.
2. When the daffodil genes are added to the rice DNA, they are
replicated along with all the other rice genes. What are the steps
taken to replicate the genes? correct answers: The DNA is unzipped, and
complementary base pairing occurs to build two separate DNA molecules.

DNA replication occurs as the DNA unzips and the bases are paired with new nucleotides.
3. Where in the daffodil cell does DNA replication occur?
correct answers: NUCLEUS DNA is found and replicated in the nucleus.
4. The golden rice plant is able to produce beta-carotene due to the
addition of new genes.
What is the first step in the production of a protein from a gene? correct
answers: TRANSCRIPTION of DNA to RNA
Transcription is the first step.
5. Where in the cells of the rice plant does transcription occur?
correct answers: NUCLEUS Transcription takes place in the nucleus where DNA
is found.
6. What is the RNA sequence produced when the following DNA
sequence is transcribed correct answers:
GGTCCAAATCTT ? correct answers: CCAGGUUUAGAA
7. After
transcription of the beta-carotene gene, the
leaves the
and binds to a ribosome to start translation. correct
answers: mRNA, NUCLEUS Transcription of this gene produces an mRNA
