DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

Answer:
D
Explanation:
The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule. This is carried out by an enzyme, called helicase which breaks the hydrogen bonds? holding the complementary bases of DNA together
Answer: True
Explanation: After a while the muscles that control your pupil size weakens which leads them to be less responsive to changes in light. Which is why older people need more light go read than a younger person does.
With age, the muscles in the iris, which control the pupil size, tend to be less responsive,leading to smaller pupils. This is a normal age-related change, but sudden drastic changes in vision should be checked by a healthcare provider.
The statement that older people tend to have smaller pupils is true. Age-related changes in the human body include alterations in the eyes and the size of the pupils especially. With age, the muscles in the iris that control the size of the pupil become less responsive, leading to smaller pupils. This can limit the amount of light that can enter the eye, thus affecting vision especially in low-light conditions.
Explanation in 100 words: The iris is a circular band of muscle that controls the size of the pupil. Aging often causes these muscles to lose some of their strength and flexibility, causing the size of the pupils to decrease. Hence, it is correct to state that older individuals usually have smaller pupils than younger ones.
In conclusion, it's important to understand that most age-related eye changes are normal and do not signify a disease. However, if drastic changes in vision occur, a healthcare provider should be consulted.
