Answer:
Oncogenes result from a mutation in  proto-oncogenes.
Explanation:
- Protooncogenes control the growth and division of cells.
 - The proteins encoded by proto-oncogenes include growth factors, growth factor receptors, transcription factors and signal transducers.
 - They contribute to the transformation process by driving cell proliferation or reducing sensitivity to cell death.
 - Several types of genetic and epigenetic changes convert these proto-oncogenes to oncogenes.
 - Oncogenes arise due to the changes that increases the expression of proto-oncogenes .
 - Oncogenes are one of the causes of cancers.
 
A proto-oncogenes can turn into oncogene by following ways:
- A point mutation  such as deletion, insertion and substitution  in the proto-oncogene can lead to formation of oncogenes. 
 - Chromosomal translocation may result in activation of proto-oncogene as seen in Burkitt's lymphoma.
 - Insertion of a mobile genetic material such as retrovirus changes the gene expression, but leaves their coding sequence intact.
 -  Activation of proto-oncogene can also occur from reduplication and amplification of DNA sequence.
 
 
        
             
        
        
        
The scientific method or scientific analysis can be defined as the objective search for the truth. When a scientist does an experiment, it is essential that he reports every observation in the result, whether it is in uniformity with the experiment or not. Many scientific discoveries are made based on the unusual findings. The failure to report these unusual findings during an experiment might result in the loss of vital information.

In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy. 
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
