Sally has been taking antibiotics for several weeks to help her fight infection antibiotics are known to disrupt the gut flora since they work by killing bacteria how would Sally’s digestive function most likely be affected by the antibiotics

Sally's digestive function would be more affected by the consumption of antibiotics due to certain vitamins might not be synthesized and foods might not break down as well.

Explanation:

Options for this question are:

Certain vitamins might not be synthesized and foods might not break down as well.Foods will not be able to be digested at all and will remain in the stomach.Sally's digestive function will not change because gut flora do not affect digestion.Sally's stomach may become bloated due to an inability to break down lactose.

The gut bacterial flora -also called intestinal microbiota- is linked to multiple metabolic and immunological functions, among others.

One of the functions of gut bacterial flora is to promote the breakdown of food into particles that can be more easily absorbed. In addition, they perform the function of synthesis of some vitamins, such as biotin, vitamins B12 and K, folic acid and pantothenic acid.

The intake of antibiotics can affect the gut bacterial flora, producing in Sally a difficulty to digest food and produce vitamins.

Like most cellular processes transcription is directed by the action of RNA Polymerase enzyme.

Explanation:

RNA Polymerase is a complex enzyme that bind to specific nucleotide sequence of the sense strand of the target DNA called promoter to initiate the process of transcription.

          There are many promoter region in both prokaryotic ans eukaryotic DNA such as TATA Box, Pribnow box for Prokaryotes and GC  Box, CAAT Box for eukaryotes.

           These promoter regions are the main binding site of RNA ploymerase ,after binding to the the promoter site RNA polymerase moves moves along the template DNA strand thus making mRNA in 5prime to 3prime direction.
