DNA is composed of sugar, phosphate and four nitrogen bases (A, T, G, C). During transcription, DNA is made into a molecule of RNA, which will travel to the ribosomes in the cytoplasm. Here, three bases, called a codon, will determine what amino acid is added to the chain. This chain will fold into a protein. This shape of this molecule determines how it functions.

Changes in the DNA code are called mutation and they can cause a protein to not function properly. A single change in the DNA of the hemoglobin gene will cause sickle cell anemia.

Explanation:

Adenine (A), Cytosine (C), Guanine (G), and Thymine are nitrogen bases. A and T pair together while C and G pair together. In DNA/RNA pairings, A pairs with Uracil (U). Transcription happens in the RNA, which is sent from the nucleus to the ribosomes (where protein is made). The three bases are called codon, their three base pairing is called an anticodon.

DNA gets mutated and this causes changes in the code. Sickle cell anemia occurs in the hemoglobin.

( Added the second part too ;) )

thinking it would be d not too sure but i think it's right

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
