Bio Beyond: Genetic Replication Questions With Complete
Solutions
- -
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
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
