Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

When the process of mitosis is correctly completed, the daughter cells should contain exact copies of all of an organisms’s genes. Which biomolecule contains all of an organism’s genes?

A	Carbohydrate
B	Lipids
C	Proteins
D	Nucleic acids

Explanation:

Detailed explanation-1: -DNA is the bio molecule that contains all of the organisms genes. when cell divides through mitosis, the daughter cells contains exact copies of DNA from both of its parents.

Detailed explanation-2: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-3: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

Detailed explanation-4: -It is important that mitosis results in the daughter cells due to growth and repair.

Detailed explanation-5: -The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.
