Answer:
The replication (exact duplication) of DNA begins with the unwinding of the double helix.
Explanation:
DNA replication is the first step of the central dogma of molecular biology which deals with the formation of 2 daughter DNA molecules from a single parental DNA.
The replcation begin with unwinding of DNA double helix by the breakage of hydrogen bonds between the complementary base pairs resulting in the formation of replication fork.
This incident occur by the catalytic activity of Helicase or dna B protein.
Answer:
The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.
Explanation:
The choice that best describes how rice was modified to create golden rice is genes from daffodils were added to rice that code for increased vitamin A production.
<h3>What is a transgenic organism?</h3>
A transgenic organism is an organism whose genome has been changed by the addition of a gene from another species.
Transgenic organism is formed as a result of the process of genetic recombination to produce organisms with better traits.
Therefore, the choice that best describes how rice was modified to create golden rice is genes from daffodils were added to rice that code for increased vitamin A production.

<span>Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.</span>
