The human genome size is 3 billion base pairs, and the size of the baker's yeast genome, a single-celled organism, is 12 million base pairs. Therefore, the predicted genome size for another single-celled organism, an amoeba, a. is about the size of the human genome b. is about the size of the yeast genome c. is somewhere between the sizes of the yeast and human genomes d. cannot be predicted with any certainty

Verified step by step guidance

1. 1. The size of an organism's genome, or the total amount of DNA it contains, does not necessarily correlate with its complexity or the number of cells it has. For example, the human genome is much larger than the yeast genome, even though both are eukaryotic organisms and yeast is a single-celled organism.
2. 2. The amoeba, like the yeast, is a single-celled organism. However, this does not mean that its genome size will be similar to that of the yeast. There are many factors that can influence genome size, including the organism's evolutionary history and the amount of non-coding DNA it contains.
3. 3. It's also important to note that there is a wide range of genome sizes among single-celled organisms. For example, some amoebas have been found to have genome sizes much larger than that of humans.
4. 4. Therefore, the genome size of an amoeba cannot be predicted based solely on the genome sizes of humans and yeast.
5. 5. So, the correct answer is (d) cannot be predicted with any certainty.
