DNA (deoxyribonucleic acid) is the building block of life, holding all of our genetic information. What organic molecules make up our DNA? Our RNA?

Amino acids are the organic molecules that make up both DNA and RNA. Specifically, DNA is made up of Adenine, Thymine, Cytosine, and Guanine. RNA is made up of Adenine, Uracil, Cytosine, and Guanine.

The periodic table was designed with trends in mind. What is the trend for electronegativity (how much an atom wants another electron) of an atom?

Electronegativity of an atom increases as the periodic table goes up and to the right. For example. oxygen is a highly electronegative atom and can be found at the top right of the periodic table.

Cells are the smallest unit of life, however, they can be broken down into smaller sections. What are the three main parts of a eukaryotic cell?

1. The cell membrane which separates the intrecellular space of the cell from the outside environment. 2. The cytoplasm, the fluid like middle of the cell made up of cytoplasm. 3. the nucleus, the center of the cell that holds genetic material.
