Which statement accurately describes sickle cell anemia?
It affects transcription and translation in humans.
It emerges in humans without the influence of DNA.
It emerges in humans without the influence of mRNA.
It affects the functions of red blood cells of humans.
It affects the functions of red blood cells of humans.
The accurate statement that describes sickle cell anemia is: "It affects the functions of red blood cells in humans."
The statement that accurately describes sickle cell anemia is: "It affects the functions of red blood cells of humans."
Sickle cell anemia is a genetic disorder that affects the shape and function of red blood cells. It is caused by a mutation in the gene that produces hemoglobin, a protein responsible for carrying oxygen in red blood cells. This mutation results in the production of abnormal hemoglobin, known as hemoglobin S.
To arrive at this answer, we can eliminate the other statements:
- "It affects transcription and translation in humans." This statement is incorrect because sickle cell anemia does not directly affect transcription (the process of creating mRNA from DNA) or translation (the process of protein synthesis from mRNA).
- "It emerges in humans without the influence of DNA." This statement is incorrect because sickle cell anemia is a genetic disorder caused by a mutation in the DNA.
- "It emerges in humans without the influence of mRNA." This statement is incorrect because mRNA plays a crucial role in protein synthesis, including the production of abnormal hemoglobin in sickle cell anemia.
Therefore, the statement that accurately describes sickle cell anemia is that it affects the functions of red blood cells in humans.
