not replicating the strand but completing it. - Answer Thymine
Adenine
Guanine
Cytosine

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? - 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? - Answer DNA has to be uncoiled
Bonds between bases have to be broken
What type of bonds are broken when the strands are split apart? - Answer Hydrogen bonds
It's important to know the base pairing rules for DNA before proceeding. Which of the following are valid
pairings for DNA? Select all that apply - Answer A-T
C-G
