Answer:
Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin — a protein that carries oxygen in red blood cells. People with two copies of the sickle cell gene have the disease.
Explanation:
Hope thia helps :)
Sickle cell anemia is caused by a single letter mutation so transcription will lead to synthesis of a different <u><em>mRNA</em></u> molecule . The different mRNA molecule will lead to a different <em><u>protein</u></em> where a single amio acid is different(there is valine instead of glutamic acid)
Answer:
The correct answer is - partially negatively charged oxygen atom of the hydroxyl group.
Explanation:
In ethanol and water, there is a hydrogen bond present in which is the strongest intermolecular bond or interaction between molecules. Water molecules contain two hydrogen atoms and one oxygen atom with the same hydrogen bond.
The oxygen atom is partially negative which is attracted to the partially positive hydrogen atom. This same attraction found between the oxygen atom of the hydroxyl group of the ethanol.
Thus, the correct answer is - partially negatively charged oxygen atom of the hydroxyl group.
It would be C, only eukaryotic cells have a nucleus
