Vedclass · Answer

(A) The process of biological nitrogen fixation in bacteria,particularly in symbiotic rhizobia,is controlled by specific gene clusters.$1$. $Nod$ genes: These genes are responsible for the nodulation process,which includes root hair curling,infection thread formation,and nodule development.$2$. $nif$ genes: These genes encode the enzymes (such as nitrogenase) and regulatory proteins required for the actual reduction of atmospheric nitrogen $(N_2)$ into ammonia $(NH_3)$.$3$. $fix$ genes: These genes are involved in the regulation and maintenance of the symbiotic nitrogen-fixing state,particularly in the bacteroid form within the nodule.Therefore,the correct cluster of genes involved in these processes is $Nod, nif, fix$.
