<h2>Answer:</h2>
Because same base pairs are arranged differently among organisms due to which there are so much variations in organisms.
<h3>Explanation:</h3>
- Variation in the organism is due to the genes.
- Every one have different DNA/genes which describes one's features.
- Genes are various arrangements of these four base pairs.
So same base pairs with different pattern arrangement causes variation among organism.
This is a process called transcription and translation.
Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed) onto messenger RNA or mRNA in short. The copying process is called transcription.
mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.
tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of the protein.
Answer: Transcription factors
Explanation:
The dioxin enters the blood stream and the fat cells and liver cells store it.
While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.
The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.
This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
