. What are "Chi (X)" DNA sequences ?

(a)           Genes synthesizing DNA polymerase

(b)          Genes helping in fragmentation + bonding of  DNA

(c)           Genes increasing recombination frequency in its vicinity DNA

(d)          Assisting in the entry of vector DNA in to the host cell

Best Answer

(c) Recombination does not occur at the same rate in all genomes in all cells at all tissues however there are certain DNA sequences called “Chi (X)” which can increase recombination frequencies in their vicinities, about five fold.
