DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes<span>, which in the language of the cell, tells cells how to make proteins. Another type of nucleic acid, ribonucleic acid, or RNA, translates genetic information from DNA into proteins.

Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.
