Q6. The bacterium Rhizobium radiobacter is well known to biologists because it has the rather astonishing ability to cause natural genetic engineering. That is, several genes are moved from the bacterial cells directly into the nucleus of cells of many higher plant species. Expression of these transferred genes in the infected plants stimulates cell division, creating a mass of undifferentiated tissue.
Which of the following signals on these transferred genes could be recognized in the plant host cell but not in the original Rhizobium cell?
“TATA” box
transcription terminator hairpin loop
intron splice signals
SD box
A. 1, 2 and 3
B. 1 and 3
C. 2 and 4
D. 4 only
E. All of 1, 2, 3 and 4
Pick two. A species of insect that lives solely on pinesap was found to contain a bacterial symbiont. Genome sequencing of both the host and the symbiont revealed that the symbiont lacked many genes required for energy production, and the host lacked genes for biosynthesis of several essential amino acids. What are the two most likely mechanisms (or, processes) that caused the loss of these genes in each partner?
Variable hypermutation rate
Transduction
Horizontal gene transfer
Natural selection
Horizontal pathogenesis
Coevolution
Selective random drift
