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.

what are the options

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
