Agrobacterium
tumefaciens is a bacterium that naturally infects plant cells.
Because it includes a plasmid with a segment called T DNA that can
be integrated into the chromosomal DNA of a plant cell, T DNA can
be used as a vector to produce transgenic plants. All of the
following steps must be included except:
a gene of interest is released into the cytoplasm to be taken up
by the T DNA
a restriction enzyme cuts a site on the T DNA vector
the T DNA is incorporated into the plant cell
chromosome
a gene of interest is inserted into the T DNA e) the
recombinant T DNA vector is transformed into A.

In the 1770’s, the
founding population of the Old Order Amish of Lancaster County, PA,
arrived from Switzerland and southern Germany. The group included
only three couples that produced offspring. In-breeding among
members of the offspring have resulted in the current population of
8,000 individuals. This population can be expected to have

Genetic drift is the
random change in allele frequencies from generation to generation.
All of the following statements about genetic drift are true
except:
Over the long run, genetic drift leads to allele fixation or
loss.
When a new mutation occurs within a population, genetic drift is
more likely to cause the loss of the new allele rather than the
fixation of the new allele.
Genetic drift promotes genetic diversity in large
populations.
Genetic drift is more significant in small populations.
