If the iodine solution was placed in a baggie and the starch solution was in the beaker, and the baggie was then submerged in the beaker, a specific chemical reaction called the iodine-starch reaction would occur.
The iodine-starch reaction is a well-known test used to detect the presence of starch in a solution. Normally, when iodine solution (iodine dissolved in water) comes into contact with starch, it forms a dark blue or black color complex.
This reaction is due to the formation of an inclusion complex between the iodine molecules and the helical structure of starch.

What is the first step of DNA replication?
A. Free nucleotides bond together in the correct sequence.
B. A single-stranded RNA molecule forms.
C. The DNA transfers its information to RNA through an amino acid.
D. The DNA molecule unzips along weak hydrogen bonds.
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
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.
