Can you please help me!? ​

Answer:

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.

Explanation:

I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.

kozerog [31]

Answer:

Chromatin

Explanation:

The unwound, filamented mass of DNA and associated proteins in a cell that is not dividing id termed as 'chromatin'. The major function of the chromatin is to pack the DNA into the compacted dense shape so that any type of tangling is avoided in the DNA strands. The chromatin is known to be present in every eukaryotic cell. It is due to chromatin that the chromosomes are properly segregated during the anaphase. The nucleus is the site where chromatin is present.
