Bio Beyond: Genetic Replication Questions
with Correct Answers
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

To continue, click on the image that you think best represents how DNA normally looks
in the cell.
First image
Looking at the images, how many chromosomes are there in a typical human?
46
What do you notice about the chromosomes in both images?
They come in pairs
, Why are chromosomes a poor way to think of how DNA is normally stored?
DNA only looks like this during replication
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
Thinking back to what you learned about genetics, what do the colored bands on the
chromosome represent?
Genes
What do the images pointing to each colored band represent?
Phenotypes
From your exploration of DNA structure and biological macromolecules, what do you
recall is the function of DNA in the cell?
Information storage
Which of the following characteristics are different between prokaryotic and eukaryotic
chromosomes?
Shape
Where is the information stored in DNA?
Base sequence
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
