Answer:
The correct answer will be- supercoiling.
Explanation:
Supercoiling is the additional twisting of the chromosomal DNA in the cell which could be either in the opposite direction of the turn or in the same direction.
Supercoiling occurs by twisting the DNA around itself which help the packaging of the large genetic material to fit into the nucleus or the cytoplasm of the cell. The supercoiling reduces the space for the DNA Packaging and allows more DNA to be packaged.
Thus, supercoiling is the correct answer.
Answer:
Neural tube defect.
Explanation:
Amniocentesis may be defined as the medical procedure that are used for the prenatal diagnosis of the chromosomal abnormalities and genetic defects. The sex of a baby can also be determined by this technique.
The amount of the α-Fetoprotein gets increased in amniotic fluid at the time of neural tube defects. The maturity of lungs is not easily determined by the 35 weeks gestation. The amniocentesis cannot be used for the detection of diabetes and cardiac disorders.
Thus, the answer is neural tube defect.
