◉ 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
