You encounter a strain of E. coli that is unable to grow or divide using lactose as a carbon source. You analyze the chromosomal genotype of these bacteria, and determine it to be: lacI- lacP lacO lacZ- lacY lacA You want to introduce an F plasmid into this bacterium in order to that restore normal lac operon function: i. e. all three protein-coding genes will be repressed in the absence of lactose and be induced in the presence of lactose. What is the minimum set of genetic elements that you must include on your plasmid in order to achieve this result

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

i don't know. if i were you, i would search it up online : d
