Answer:
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
Answer:
A. True
Explanation:
Hemoglobin is a protein and has two distinct types of polypeptide chains. These are called the alpha and beta subunits. The gene that code for the beta chain undergoes a mutation in a single base that causes sickle cell anemia. Here, adenine base in the genetic code for glutamic acid is substituted with a thymine base.
The genetic code for glutamic acid in the beta chain gene is GAG. The "A" is replaced with "T" and the new code "GTG" codes for valine. Therefore, the mutated hemoglobin has valine in place of glutamic acid. This makes these mutated protein molecules to form aggregates resulting in a change in the shape of RBCs carrying them.
