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.
B. Burning point
C. Boiling point
D. Chemical stability
Boiling point. If you boil water it changes from a liquid to a gas, which is a physical change. The rest are chemical properties because the chemical make up of an object changes.
Answer:
hope this makes sense
Explanation:
In an experiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: The difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group.
Knowing the correct order of information, specifically state what is occurring in Process #1 and in Process #2.
Please be very specific in your answer as i cannot assume which blank and process you are referring to. Be sure to provide this information and to have your blanks noted in the correct order

Answer:
The central dogma of molecular biology explains the flow of genetic information, from DNA ?to RNA?, to make a functional product, a protein?.
The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes?.
The ribosomes serve as factories in the cell where the information is ‘translated’ from a code into the functional product.
The process by which the DNA instructions are converted into the functional product is called gene expression?.
Gene expression has two key stages - transcription? and translation?.
In transcription, the information in the DNA of every cell is converted into small, portable RNA messages.
During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are ‘read’ to make specific proteins.
The central dogma states that the pattern of information that occurs most frequently in our cells is:
From existing DNA to make new DNA (DNA replication?)
From DNA to make new RNA (transcription)
From RNA to make new proteins (translation).

Reverse transcription is the transfer of information from RNA to make new DNA, this occurs in the case of retroviruses, such as HIV?. It is the process by which the genetic information from RNA is assembled into new DNA.
Does the ‘Central Dogma’ always apply?
With modern research it is becoming clear that some aspects of the central dogma are not entirely accurate.
Current research is focusing on investigating the function of non-coding RNA?.
Although this does not follow the central dogma it still has a functional role in the cell.
