But in fact, the truth may be hidden in this ordinary-looking piece of meteorite known as Rock 84-001.
The report discusses the possibility of life on Mars and explores the life's probable origins. The thesis statement brings our attention to the main topic of the report, which indicates that the report will focus on the piece(s) of evidence found in this specific meteorite.
Answer:
The correct answer is The drug binds to the 30S small ribosomal subunit eukaryotes have 40S small sub unit.
Explanation:
Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.
Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.
As eukaryotes contain 40S ribosomal subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.
Without a control group there wouldn’t be any basis for knowing if a result is due to the variable being tested
