Aresearcher is preparing to insert a human gene of interest into a bacterial plasmid in order to clone the human gene. she has genetically engineered the plasmid to carry a gene amp r , which confers resistance to the antibiotic ampicillin. she will include ampicillin in the plating medium when she grows the recombinant bacteria. why has she engineered the plasmid to include an antibiotic resistance gene?

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
