Bill Activity #40
To Think About: How is DNA, and in some cases RNA, the primary source of heritable information? How
is heritable information passed to the next generation in eukaryotes, and how do changes in genotype
result in changes in phenotype of an organism?
1st Interact: Take notes on Mr. Andersen’s DNA and RNA Part 1 Video by using the flow chart and video
guide http://www.bozemanscience.com/027-part-1-dna-rna
2nd Read About: The Molecular Basis of Inhertance: Pgs. 305-322 Campbell’s Biology 9th edition
 DNA is the genetic material
o Summarize the research of the following people: Griffith (and transformations), Avery,
McCarty and MacLeod, Hershey and Chase, Chargraff, Wilkins and Franklin, Watson and
Crick
o Describe the structure of DNA and the building blocks (nucleotides), explain the
difference between purines and pyrimidines
 Many proteins work together in DNA replication and repair
o Explain the purpose of DNA replication and why it is called semiconservative
o Study the text and diagrams on pgs. 313-319. List and define the following: origins of
replication, replication fork, helicases, single-stranded binding proteins, topoisomerase,
primer, primase, DNA polymerase, leading strand, lagging strand, Okazaki fragments,
DNA ligase
o Describe how proofreading occurs, include definitions of nuclease and nucleotide
excision repair
o Explain the role of telomerase
 A chromosome consists of a DNA molecule packed together with proteins
o Describe the difference between a bacterial chromosome and a eukaryotic chromosome
(also explain the difference between heterochromatin and euchromatin.
