The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.

The question is incomplete as it does not have the attached DNA gel which has been attached.
Answer:
No
Explanation:
In the given question, the DNA of the boy was compared with the DNA samples of his father and mother.
The DNA if these people were collected and PCR was performed to duplicate the DNA. These DNA samples were then analysed on the Gel electrophoresis in which the bands were visualized with the UV light.
In the band, we observe that the size of the DNA fragments was not similar to the DNA sample of the women but a band was of similar size to the father.
Since the bands are of different size of the boy when compared to the mother, therefore, the women are not the mother of the boy.
Thus, No is the correct answer.
