31.   On the other hand, the researchers found that the cell nuclei showed similarities worldwide.

32.   Paramecia, cell nucleus, long spiraling molecules of DNA.

33.   The empty eggs and the transferred cell nuclei fused and grew into blastocysts, an early embryonic stage that resembles a ball of cells.

34.   The method vividly demonstrates the mayhem rendered when atomic particles rip through molecular bonds in cell nuclei, leaving behind scrambled DNA and cancer-vulnerable tissue.

35.   They looked at mitochondrial DNA which is outside the cell nucleus and passed down only by the female of a species.

36.   They also looked at the genetic material in the cell nucleus which is possessed by both parents.
