Jamie is a 24-year-old female with a urinary tract infection. She is healthy, afebrile, and her only drug allergy is sulfa, which gives her a rash. An appropriate first-line antibiotic choice for her would be:

Ciprofloxacin would be the appropriate first-line antibiotic choice

Explanation:

Ciprofloxacin are fluoroquinolones which belong to broad-spectrum antibiotics used to treat many bacterial infections especially of the gastrointestinal and urinary tracts, eye, ear, skin, etc.

Ciprofloxacin is considered as the first line of antibiotic in most of the uncomplicated urinary tract infections, like in the above case, Jamie is afebrile and healthy but with sulfa allergy.

Since she is allergic to sulfa drugs, antibiotics containing sulfa like azithromycin or ceftrioxone should not be prescribed for Jamie as they may cause skin rash hives or irritation, eye itching, and other allergic reactions.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
