What is the relationship between proto-oncogenes and oncogenes?

SCORPION-xisa [38]3 years ago

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 plane that separated the body into superior and inferior portions is a sagittal plane.
dybincka [34]

Answer: False  

Explanation:

The saggital plane divides the body into two halves based on the fact that the body is segmented into left and right planes.

The plane may be away or at can lie at the center of the body and it splits the body into parts. It  may be far or close to the midline of the body. It may also split the body into two unequal parts.

The term saggital is coined by Gerard Cremona.

Imagine you are an engineer who needs to test a scale model of a
FinnZ [79.3K]

Answer:

The problem will be because:

  • <u>The error in the construction of the bridge will be actually 40 cm</u>.

Explanation:

When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, <em><u>from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error</u></em>.
