Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....
Answer:
Propofol (another name Diprivan) can be used for Diana's surgery. It is a sedative or anesthesia commonly used for children and adults. Studies show that there were no significant differences in dose requirements based on sex or age, except for the too elderly. The difference in dosing considering different body weights were not statistically significant also. The same dose is safe
( 0.1-0.15 mg/kg/min IV for 3-5 min) for Diana, the 210 lb man or a 10-year-old girl. However, the dose was higher in patients with bradycardia and hypotension.
