Certain viruses are instrumental in converting proto-oncogenes to oncogenes. This conversion most ordinarily results because:. the proto-oncogenes are more likely to undergo mutation or recombination within an epidemic .
How does a proto-oncogene become converted into an oncogene?
The conversion of a proto-oncogene to an oncogene is named activation. Proto-oncogenes can become activated by a spread of genetic mechanisms including transduction, insertional mutagenesis, amplification, point mutations, and chromosomal translocations.
What is the function of a proto-oncogene?
Proto-oncogenes are normal genes which affect normal cell growth and proliferation, but which have the potential to contribute to cancer development if their expression is altered. a spread of events may activate proto-oncogenes and convert them from benign genes to cancer genes.
What is the relationship between proto-oncogenes and oncogenes?
Oncogenes are mutant sorts of proto-oncogenes. Proto-oncogenes are normal cellular genes. Mutations can cause these to be permanently switched on, resulting in uncontrolled cell division and cancer.

Answer:Rearrangement occurs during meiosis when the chromosomes line up in homologous pairs during metaphase I and II. Independent assortment occurs when tetrads randomly align at metaphase plate. Then the chromosomes separate during anaphase I and II; each gamete receives one of each type of chromosome. During prophase I, Crossing over occurs with tetrads at chiasmata resulting in genetic variation.

<span>There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material</span>
Answer:
It requires energy
Explanation:
In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
