Answer;
D. Meiosis ii of mother
Explanation;
-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.
-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
I think the correct answer is B
Answer:
Fluorescence-Activated Cell Sorting or FACS is a method that allows us to sort out different cell types on the basis of fluorescence emitted by cell membrane components bound compounds.
In the case of CD95 integral protein which is known for highly glycosylated, if use antibodies against cells with CD95 marker, will not identify glycans and can’t be targeted by antibodies as antibodies only recognize protein structures.
Therefore, two different proteins should be used in order to get the correct sorting of cells. One of these would bind to these glycosylations, and the other would be antibodies (with a fluorescent tag) against first.
