A researcher would like to map the location of galE and trpA genes in a new species of bacterium that appears to be closely related to E. coli. He decides to use cotransduction, and generatesnappropriate donor and recipient strains. He is disappointed when cotransduction is not seen in his experiement. What is the most reasonable explanation for this situation?

#Section 3: Genetics, Cellular and Molecular Biology
  1. His new bacterial species does not have galE or trpA genes.

  2. His new bacterial species cannot survive galE or trpA mutation.

  3. These two genes are too far apart to be mapped by cotransduction.

  4. These two genes are too close together to be mapped by cotransduction

Which of the following statement is true?
A) PAM matrices are derived from an evolutionary model whereas the BLOSUM matrices consist of entirely direct observations. 
B) Because of BLOSUM matrices have less evolutionary meaning that is why the PAM matrices are used most often for reconstructing phylogenetic trees.
C) BLOSUM matrices are entirely derived from local sequence alignments of conserved sequence blocks, whereas the PAM matrix is based on the global alignment of full-length sequences.
D) BLOSUM matrices are more advantageous in searching databases and finding conserved domains in proteins.
