Deletion, substitution or addition cause mutation that alters the sequence of the stop codon. These can lead to change the structure of the codon. If a stop codon is altered to any other codon, the codon will start coding for that amino acid and the synthesis of polypeptide continues and some another protein is formed in the place of original polypeptide.
Answer:
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Explanation:
<span>The advantage that the phylogenic classification system has over the Linnaean system is that the phylogenic system defines each organism as a plant or animal; The Linnaean system does not. Apparently, this is a huge flaw that the Linnean system has, because it is quite important to distinguish between plants and animals, especially in such cases when it is not obvious at the first glance.</span>
