BIO BEYOND GENETIC REPLICATION UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS VERIFIED 2027 EDITION
1.
2. Which bases pair in DNA? In the simulation below, build the strand that is complementary to the
one shown. In this case, you are not replicating the strand but completing it.
Thymine Adenine Guanine Cytosine Cytosine Thymine Thymine Adenine Guanine Thymine
3. To continue, click on the image that you think best represents how DNA normally looks in the cell.
First image
4. Looking at the images, how many chromosomes are there in a typical human?
46
5. What do you notice about the chromosomes in both images?
They come in pairs
6. Why are chromosomes a poor way to think of how DNA is normally stored?
DNA only looks like this during replication
7. The top image, called a karyogram or karyotype, is from a human female, while the bottom one is
from a human male. What major difference do you notice?
The male has a set of mismatched chromosomes
8. Thinking back to what you learned about genetics, what do the colored bands on the chromosome
represent?
Genes
9. What do the images pointing to each colored band represent?
Phenotypes
10. From your exploration of DNA structure and biological macromolecules, what do you recall is the
function of DNA in the cell?
Information storage
11. Which of the following characteristics are different between prokaryotic and eukaryotic
chromosomes?
Shape
12. Where is the information stored in DNA?
Base sequence
13. Looking at the image to the right, what has to be done to chromatin before the information in it
can be accessed?
It has to be unwound to uncoiled DNA
14. From chromatin, two major processes are needed to prepare for DNA replication. Watch the video
at right - what processes are needed before new DNA can be made?
DNA has to be uncoiled Bonds between bases have to be broken
