Urinary
retention - the inability to urinate - is a common post-operative
complication, and can have serious ramifications for patients. Most
specifically, this condition, if allowed to persist, can cause damage to the
bladder, as urine builds up in the organ to dangerously high levels. Retained
urine can also lead to infections, which can cause systemic issues in
patients.

Semen is a mixture of sperm and seminal fluid, a liquid that consists of the secretions of the seminiferous tubules, seminal vesicles, prostate, and bulbourethral glands.
The seminal fluid (which is primarily composed of water, fructose, proteins, minerals, and other micronutrients) provides the sperm with a transportation medium, nutrients, and protection from the hostile acidic environment of the male’s urethra and the female’s vagina.
<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
