BIO BEYOND GENETIC REP UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS VERIFIED 2027 EDITION
1. 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
Drag and scroll down
2. To continue, click on the image that you think best represents how DNA normally looks in the cell.
crhomosome pic
3. Looking at the images, how many chromosomes are there in a typical human?
46
4. What do you notice about the chromosomes in both images?
They come in pairs
5. Why are chromosomes a poor way to think of how DNA is normally stored?
DNA only looks like this during replication
6. 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
7. Thinking back to what you learned about genetics, what do the colored bands on the chromosome
represent?
Genes
8. What do the images pointing to each colored band represent?
Phenotypes
9. Which of the following characteristics are different between prokaryotic and eukaryotic
chromosomes?
Shape
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. Where is the information stored in DNA?
Base seq
12. 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
13. 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? Select all that apply.
DNA has to be uncoiled Bonds between bases have to be broken
14. What type of bonds are broken when the strands are split apart?
Hydrogen bonds
