Choose the true statements about amyloid fibrils. 3 options are correct.
1) Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
2) An amyloid fibril typically forms from aggregates of misfolded peptides resulting from frameshift mutations.
3) An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
5) Proteins that convert to an amyloid fibril structure tend to have low solubility in their native form.

Options 1, 3 and 4.

Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.

An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.

4) Soluble proteins that misfold and form amyloid fibrils become insoluble.

Explanation:

Amloid fibrils are peptide or proteins that are formed during invivo or invitro conditions. They ate formed when soluble proteins combine together to for insoluble fibres that are resistant to degradation. They are found in extracellular tissues and posses pathological effect. They accumulate after nerve cells and causes several illness.

An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.

4) Soluble proteins that misfold and form amyloid fibrils become insoluble.

An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.

Soluble proteins that misfold and form amyloid fibrils become insoluble.

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.
