Bio Beyond: Genetic Replication questions
and answers 2026\2027 A+ Grade
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.
- correct answer 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.
- correct answer First image
Looking at the images, how many chromosomes are there in a typical human?
- correct answer 46
What do you notice about the chromosomes in both images?
- correct answer They come in pairs
, Why are chromosomes a poor way to think of how DNA is normally stored?
- correct answer 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?
- correct answer 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?
- correct answer Genes
What do the images pointing to each colored band represent?
- correct answer Phenotypes
From your exploration of DNA structure and biological macromolecules, what do you recall is the
function of DNA in the cell?
- correct answer Information storage
Which of the following characteristics are different between prokaryotic and eukaryotic chromosomes?
- correct answer Shape
Where is the information stored in DNA?
- correct answer Base sequence
Looking at the image to the right, what has to be done to chromatin before the information in it can be
accessed?
- correct answer It has to be unwound to uncoiled DNA
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?
- correct answer DNA has to be uncoiled
Bonds between bases have to be broken
