| Question | Answer |
|---|---|
| Proteins have [...] levels of structure. | Proteins have four levels of structure. |
| A protein is a large molecule made of two or more [p-] chains. | A protein is a large molecule made of two or more polypeptide chains. |
| Each polypeptide is made up of chains of [...] acids—molecules composed of carbon, hydrogen, nitrogen, and oxygen. | Each polypeptide is made up of chains of amino acids—molecules composed of carbon, hydrogen, nitrogen, and oxygen. |
| The four structural levels of proteins: 1. Primary Structure: [...] 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure | The four structural levels of proteins: 1. Primary Structure: amino acid sequence 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure |
| The four structural levels of proteins: 1. Primary Structure: 2. Secondary Structure: [...] of close-regions caused by [...] bonds between amino acids 3. Tertiary Structure 4. Quaternary Structure | The four structural levels of proteins: 1. Primary Structure: 2. Secondary Structure: folding of close-regions caused by hydrogen bonds between amino acids 3. Tertiary Structure 4. Quaternary Structure |
| The four structural levels of proteins: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure: Folding of [...] regions cased by bonds between [...] of amino acids 4. Quaternary Structure | The four structural levels of proteins: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure: Folding of distant regions cased by bonds between R-groups of amino acids 4. Quaternary Structure |
| The four structural levels of proteins: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure: how [...] fit together | The four structural levels of proteins: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure: how two or more polypeptide chains fit together |
| Individuals with the inherited disorder called [...]-cell anemia have red blood cells with a sickle shape that causes them to get stuck in small blood vessels. | Individuals with the inherited disorder called sickle-cell anemia have red blood cells with a sickle shape that causes them to get stuck in small blood vessels. |
| Sickle-shaped blood cells are caused by a change in just [...] of the amino acids in the hemoglobin molecule. | Sickle-shaped blood cells are caused by a change in just one of the amino acids in the hemoglobin molecule. (it should be glutamic acid, but in sickle cells, it's usually valine) |
| A sickle is a harvesting tool. It's basically a crescent-shaped knife used to cut bunches of grain or other plant crops. The sickle and star were symbols on the flag of the [...]. | A sickle is a harvesting tool. It's basically a crescent-shaped knife used to cut bunches of grain or other plant crops. The sickle and star were symbols on the flag of the Soviet Union. |
