BIO BEYOND GENETIC REPLICATION EXAM
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. - ANS -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. - ANS -First image
, Looking at the images, how many chromosomes are there in a typical
human? - ANS -46
What do you notice about the chromosomes in both images? - ANS -
They come in pairs
Why are chromosomes a poor way to think of how DNA is normally
stored? - ANS -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? - ANS -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? - ANS -Genes
What do the images pointing to each colored band represent? - ANS -
Phenotypes
From your exploration of DNA structure and biological macromolecules,
what do you recall is the function of DNA in the cell? - ANS -Information
storage
