Antibiotic resistance in bacteria is the result of A) binary fission.
B) nitrogen fixation
C) genetic variation.
D) genetic engineering.

Answers

Antibiotic resistance in bacteria is the result of genetic variation.

What is Genetic variation?

DNA sequence variations among members of a population are referred to as genetic variation. Sperm and egg cells, as well as somatic (all other) cells, are subject to variation.

Only variation that develops in germ cells can be passed from person to person and hence influence population dynamics and, in turn, evolution.

Genetic variety first appeared as a result of mutations. A mutation is a type of DNA sequence change that is permanent. When a mistake in DNA replication occurs and is not fixed by DNA repair enzymes, de novo (new) mutations take place.

Therefore, Antibiotic resistance in bacteria is the result of genetic variation.
