Vestigial structures are taken as an example of evolution because they give us an indication of structures that, due to the adaptation to the environment, disappeared.
At the end of the vertebral column, we have the coccyx as an example of this. Its believed that it could have formed a tail and currently, is only a small bone without any specific function, even some individuals are born without it.
Answer:
Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.
Explanation:
After treating the wild type and experimental RNA with amanitin solution, the amanitin actively binds to the active site of wild type RNA polymerase, inhibiting addition of nucleotides and also it interferes with the motility of RNA pol. along the DNA template, due to which their is a sharp decline in maximum elongation rate of mRNA. In case of experimental RNA polymerase, due to single base substitution the experimental strain is already having very low elongation rate, but binding of amanitin causes constraint on the motility of RNA polymerase through the DNA template, thereby decreasing the elongation rate. Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.
The sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.
<h3>What are Nucleotides?</h3>
Nucleotides may be defined as a molecule that consists of a nitrogen-containing base, a phosphate group, and a pentose sugar.
The codons that codes for the given amino acids are as follows:
- Phe = UUC
- Ser = UCC
- Gln = CAA.
mRNA is synthesized from a template DNA strand based on a complementarity mechanism.
Therefore, the sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.

Answer:
Gabriel's horn
Explanation:
What the question is asking for is a 3-dimensional shape that has a lot of surface area and only a little volume. The first thing I thought of was a geometric figure called Gabriel's Horn. A quick search on Wikipedia will explain better than I can, but basically it has infinite surface area but finite volume. You probably couldn't test the shape in any experiment, though, since it's only theoretical and can't exist in real life.
Let me know if I can explain anything in a clearer way!
