If protein is the heritable material, how many unique sequences of 10 amino acids
are possible?✔✔20¹⁰
If DNA is the heritable material, how many unique 10 DNA base pair sequences are
possible?✔✔4¹⁰
Which biomolecule can encode the most unique sequences for a given
length?✔✔Protein
Based on Griffith's experiments, where can you conclude the heritable material is
located?✔✔Loosely attached to the cell wall/membrane
Which of the following could be used as a negative control in the Avery
experiments?✔✔Buffer solution only

plates of R cells and tubes of the extracted S factor. In which of the following cases
would you see the R cells be transformed into S cells.✔✔All of the above EXCEPT
when you add S factor + DNAase
Based on the results of Avery's experiments, which biomolecule most likely
constitutes the heritable material?✔✔DNA
In Table 1.2, which biomolecule was more likely to be found inside the cell?✔✔DNA
Which DNA base pairs contain two rings?✔✔Adenine and Guanine
The nitrogenous bases are held together by which kind of bonds?✔✔Hydrogen
bonds
What method of replication did Meselson & Stahl determine was used in DNA
replications?✔✔Semi-conservative
If DNA replication was conservative, after one generation how many bands in the
Meselson & Stahl experiments would you expect?✔✔2
The following image is of DNA bands following 2.5 generations as well as a
quantification of the density of both bands. Which of the bands contains the most
DNA?✔✔A (thicker, darker band)
In an adult, the gene encoding the fetal hemoglobin protein is most likely to
be✔✔Hypermethylated
