The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
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:
Ring-Necked Pheasants
Explanation:
Ring-Necked Pheasants are known to be nest parasites to the Prairie-Chicken and can disrupt Booming Grounds and Feeding Areas. This puts Prairie-Chickens under the endangered list.
Answer:
The cells of the body's surface form the outer layer of skin. Inside the body, epithelial cells form the lining of the mouth and alimentary canal and protect these organs. Epithelial tissues help in absorption of water and nutrients
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Explanation:
Answer:
defoliants - cause plants to drop their leaves
fungicides - used to control fungal problems like mold, mildew and rust
insecticides - used to control insects
rodenticides - used to kill rodents like mice, rats, and gophers
foggers - used to kill insects that are in the open and touch the pesticides
herbicides - kill or inhibit the growth of unwanted plants ( weeds )
