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.

An invasive species, such as the trees in your question, could:

- Out compete the native flora for resources, such as nutrients.

- An earlier reproductive and faster growing cycle could quickly surpass native tree growth.

- This alien species taking the place of native trees could disrupt the habitat of animal species that need the native flora instead.

o-na [289]
Central dogma is done by all cells which involves the process of DNA replication, transcription and translation. DNA replication involves making of a new DNA molecule  to copy the genetic information and takes place in the nucleus of a cell while Transcription is the formation of a mRNA from DNA molecule by RNA polymerase a process that takes place in the nucleus. Translation involves formation of polypeptides from the messenger RNA which takes place in the cytoplasm (cytosol) of both prokaryotic and eukaryotic cells in an organelle known as ribosomes.
