Responses
It emerges in humans without the influence of mRNA.
It emerges in humans without the influence of mRNA.
It emerges in humans without the influence of DNA.
It emerges in humans without the influence of DNA.
It affects the functions of red blood cells of humans.
It affects the functions of red blood cells of humans.
It affects transcription and translation in humans.
It affects the functions of red blood cells of humans.
The statement that accurately describes sickle cell anemia is: "It affects the functions of red blood cells of humans."
The correct answer is: "It affects the functions of red blood cells of humans."
To understand this, we can break down the options provided:
1. "It emerges in humans without the influence of mRNA." - This statement is incorrect because all biological processes, including the emergence of sickle cell anemia, are influenced by mRNA (messenger RNA) since it plays a crucial role in protein synthesis.
2. "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 sequence that codes for the hemoglobin protein.
3. "It affects the functions of red blood cells of humans." - This statement is correct. Sickle cell anemia is a genetic disorder that affects the structure and function of red blood cells. The mutation in the DNA sequence causes red blood cells to become abnormally shaped, leading to various health problems.
4. "It affects transcription and translation in humans." - This statement is incorrect. Although sickle cell anemia involves genetic mutations, it does not directly affect the processes of transcription and translation, which are responsible for protein synthesis.
