<h2>Question:- </h2>
If you are to conduct a DNA analysis using a blood sample which of the blood components will you use
<h2>Options :- </h2>
1.) Red Blood Cells
2.) White Blood Cells
3.) Plasma
4.) Platelets
<h2>Answer:- </h2>
Option 2.) White Blood Cells
<h2>Explanation:- </h2>
- Red Blood Cell(RBC) , Plasma , Platelets lack DNA
- White Blood Cell (WBC ) only have DNA
- RBC lack nucleus to make space for O2 as the work is to carry O2 with help of hemoglobin
- Platelets are the cell fragments of the large cells they help in clotting so too lack nucleus
- Plasma is the fluid part of the blood. so it contain water in its most part and too lack DNA bez plasma don't contain any cells
- WBC are the only cells which have well defined nucleus with DNA in above mentioned options
It can filter less water out of the blood.!
