CERTIFICATION TEST PAPER 2026 COMPLETE
SOLUTIONS GRADED A PLUS
◉ To continue, click on the image that you think best represents how
DNA normally looks in the cell.
Answer: First image
◉ Looking at the images, how many chromosomes are there in a
typical human?
Answer: 46
◉ What do you notice about the chromosomes in both images?
Answer: They come in pairs
◉ Why are chromosomes a poor way to think of how DNA is
normally stored?
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?
, 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?
Answer: Genes
◉ What do the images pointing to each colored band represent?
Answer: Phenotypes
◉ From your exploration of DNA structure and biological
macromolecules, what do you recall is the function of DNA in the
cell?
Answer: Information storage
◉ Which of the following characteristics are different between
prokaryotic and eukaryotic chromosomes?
Answer: Shape
◉ Where is the information stored in DNA?
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?
