It's actually pretty easy to estimate the first number - all you have to know is the apparent angular size of the sun and moon in the sky (about half a degree each) and the the time it takes the moon to orbit the earth (about one month).
Eukaryotic Organelles. 1  Nucleus-a membrane bound structure that contains the cell's hereditary (DNA) information and controls the cell's growth and reproduction. 2  It is commonly the most prominent organelle in the cell.
In eukaryotic cells, mitochondria and chloroplasts a â¦ lso contain DNA, which performs replication and transcription inside these organelles. In prokaryotic cells there is no nucleus. The DNA is in a region of the cytoplasm called the nucleoid, and that is where DNA replication and transcription occur in these cells.
