The human gene EGFR located on chromosome 7 is a proto-oncogene that codes for a growth factor cell surface receptor. The binding of growth factors to this receptor can lead to cell proliferation. Hypothesize what potential impact a mutated EGFR allele will have on a cell. Give one possible impact and explain your answer.

Explanation:

The human gene EGFR  is a proto-oncogene that codes for a growth factor cell surface receptor, the mutated proto-oncogene becomes oncogene when mutated, which causes uncontrolled cell proliferation.

A mutated EGFR gene causes the up-regulation of the growth factor receptors. This causes an abnormally high levels cell growth even when growth factors have not bound the receptor. It  causes the epidermal cells to proliferate even without growth factor. This unregulated growth causes cancer such as adenocarcinoma.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
