A codon is a sequence of three nucleotides in DNA or RNA that codes for either a particular amino acid or tells the cellular machinery to start or stop using the code. It isn't located anywhere specific.
Salivary amylase is an enzyme that is found in saliva in the mouth. It is an enzyme that only recognizes the glycosidic bonds between molecules of simple sugars that form the carbohydrate polymers.
It specifically targets these bonds and breaks them and does not recognize any other bonds of different substances such as protein.
Salivary amylase is alkaline in nature and cannot work in the stomach. It breaks the glycosidic bonds between the glucose molecules in starch to form maltose. Maltose is later broken down further by pancreatic amylase, into individual units of glucose.
Answer:
Excess tissues fluid that has leaked out of capillaries.
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.
You can use the translucent test, lipids leave a translucent trace when smouldered on paper
or you can just use sudan III solution
