Answer:
<u>D) the nucleic acid (either DNA or RNA)</u>
<u />
Explanation:
Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.
The nucleic acids are made up of nucleotides. These are genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).
Answer:
Antibiotic resistance occurs when bacteria do some variation in their genome that allows bacteria to eliminate the effect of antibacterial drugs. Irregular or excessive antibiotics use is the main cause of generating antibiotic resistance bacteria.
So antibiotics should be taken only on the prescription of doctors and a complete course of antibiotics should be done to eliminate all the bacteria so that no bacteria is left to generate antibiotic-resistant bacteria.
Antibiotics should be avoided in viral infection as antibiotic does not kill viruses as it is only beneficial in bacterial infection.
