Leucocytes

Vedclass · Answer

(A) The correct answer is $A$. $DNA$ profiling or $DNA$ fingerprinting requires nucleated cells to extract genomic $DNA$. $Leucocytes$ (white blood cells) are nucleated cells found in blood,making them the ideal source for $DNA$ extraction. $Platelets$ are cell fragments lacking a nucleus. $Erythrocytes$ (mature red blood cells) in humans lack a nucleus and organelles. $Serum$ is the liquid component of blood remaining after clotting,which does not contain cells or $DNA$.

Blood stains are found at the site of a murder. If $DNA$ profiling technique is to be used for identifying the criminal,which of the following is ideal for use?
