It is thought that all eukaryotes have about 300 genes in common. Would you predict that these genes would be used at different times during the life cycle of multicellular animals? Explain your answer
What will be an ideal response?
No, these genes are likely to be involved in basic cellular functions such as DNA replication and protein production, and in the basic functions of eukaryotic cells such as the functioning of the nucleus and the movement of items between cellular compartments. Genes involved in basic cellular functions are likely to be used all the time in an organism's life and are not likely to be activated at a specific stage of life. The genes found in all eukaryotes probably existed in the primordial eukaryotic cells.
