In DNA isolation from blood which cells are the DNA source?

Answer and explanation

Correct answer: White blood cells

White blood cells contain nuclei, so their nuclear DNA can be isolated from a blood sample. Mature mammalian red blood cells lack nuclei, while platelets are cell fragments and are not a suitable source of genomic DNA. Salts in plasma are not cells. Exam tip: For genomic DNA isolation from blood, choose white blood cells.
