Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.

No, the sickle-cell anemia allele won't be eliminated by natural selection.
Sickle-cell anemia trait is controlled by a single gene and the allele (S) for sickle-cell anemia is a harmful autosomal recessive.
It is caused by a mutation in the normal allele (A) for hemoglobin (a protein on red blood cells).
Heterozygotes (AS) with the sickle-cell allele are resistant to malaria, a deadly tropical disease. It is common in many African populations.
In these areas, (S) carriers have been naturally selected, because their red blood cells, containing some abnormal hemoglobin, tend to be in sickle shape when they are infected by the malarial parasite.
Therefore, they are more likely to survive and reproduce. This keeps the S allele in the gene pool.

Answer:
interphase → prophase → metaphase → anaphase → telophase → cytokinesis
Explanation:
Base on the scenario been described in the question, Rahul looks at six unlabeled slides showing different stages of the cell cycle the correct Rahul to place the slides in order, starting with interphase is as follows
interphase → prophase → metaphase → anaphase → telophase → cytokinesis
This is the correct order Rahul should place the slides.
