Which of the following experimental results was NOT evidence that DNA is the genetic molecule rather than proteins? a. When a virus was radioactively labelled, and the virus was allowed to infect a bacteria cell, radioactive virus DNA was found inside the bacteria cell while radioactive virus proteins were found outside the cell. b. Dead pathogenic bacteria cells combined with living nonpathogenic bacteria cells caused the creation of living pathogenic cells and thus the death of the host animal. c. Proteins are a class of macromolecules with the diversity and specificity needed for hereditary material. d. Nucleotide bases occur regularly, such that the number of adenines = number of thymines, and the number of guanines = number of cytosines.

Place the steps of sanger sequencing in order.A. A fluorescent laser excites the fragments and records the wavelength consistent with a single nucleotide. B. ddNTPs bind and stop chain extension.C. DNA fragments are separated by size through a capillary tube. D. DNA polymerase copies the target region of template DNA.E. The final nucleotide of each fragment is labeled with a fluorescent tag.

A researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely? A. All of the bacterial DNA consists of coding sequences, but this is not true of the eukaryotic DNA. B. There are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. C. There are densely packed genes in the eukaryotic DNA that were not immediately distinguishable during the first analysis. D. The bacteria have larger quantities of noncoding DNA than the eukaryotic cells.
