You isolate the nucleolus from the nucleus and performed a density gradient centrifugation with the extract. Then you check the different for the RNA polymerase activity of the different segment. Which RNA polymerase would you expect to find in abundance?

You isolate the nucleolus from the nucleus and performed a density gradient centrifugation with the extract. Then you check the different for the RNA polymerase activity of the different segment. Which RNA polymerase would you expect to find in abundance? Correct Answer RNA pol I

Nucleolus is the centre for rRNA production. As RNA pol I is mainly concerned with rRNA transcription we will expect to find this in abundance. Cytosolic extract on the other hand will be abundant in RNA pol II and III.

Consider the following statements regarding double fertilization and choose the correct answer:
1. At the time of the sperm's approach to the egg nucleus, the male nucleus has the appearance of a continuous thread rolled into a ball
2. It is only the presence of the two nucleoli which serves to distinguish the fertilized egg from the unfertilized egg
3. Finally, the male nucleolus increases in size and fuses with the female nucleolus thus closing the phenomenon of sexual union of the nuclei
4. The fusion of the male gamete with the secondary nucleus results in the formation of a sister embryo
