Viruses, not bacteria, cause cold and flu. however, some people demand antibiotics from their doctors to control the symptoms of these diseases. do you think the use of antibiotics in these situations has an effect on antibiotic-resistant bacteria?

Overuse of antibiotics will have an effect on the number of resistant bacteria. Overusing antibiotics will increase the number of antibiotics in the environment. Over time, bacteria with a genetic resistance to these drugs will grow and multiply faster than those that do not have resistance. As a result, the number of drug-resistant bacteria in the environment will increase.

explanation:

carbon can form so many different compounds not just with oxygen

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.
