Sentences with phrase «resistant genes»
"Resistant genes" refers to specific genes in organisms that provide them with the ability to fight off, withstand, or be unaffected by certain diseases, infections, or treatments. These genes make the organisms less susceptible to harm or damage caused by external factors or medical interventions. Full definition
