What do chaperones do?
- Carry the folding blueprint for each new chain made
- Block wrong contacts and shield sticky patches
- Snap the weak bonds of the fold
Where is the folding information stored?
- The amino acid sequence itself
- The chaperone that guards the chain
- The aggregate clump at the end
Misfolded chains clump into aggregates that poison cells. True or false?
Circle one: True False
What happens in denaturation?
- The sequence is rewritten with new amino acids
- Chaperones multiply to refold the chain
- Heat snaps weak bonds and unravels the chain
What does misfolding have to do with Alzheimer and prion illnesses?
- Misfolded proteins are missing entirely from cells
- Misfolded proteins stack into harmful clusters
- Too many chaperones blocking the fold
A new chain folds by following a fixed step by step recipe. True or false?
Circle one: True False
Chaperones are needed because the sequence carries no folding plan. True or false?
Circle one: True False
A boiled egg can turn runny again if it is cooled. True or false?
Circle one: True False
How chains find their shape W1-mt_n9rlqjbaXK-s1
- Block wrong contacts and shield sticky patches · They keep chains apart while folding, adding no information.
- The amino acid sequence itself · The sequence holds the blueprint; guarding only raises how many reach the shape.
- True · Nerve cells clear the clumps badly, so they pile up and harm tissue.
- Heat snaps weak bonds and unravels the chain · Broken weak bonds undo the fold, and function is usually lost.
- Misfolded proteins stack into harmful clusters · Harmful shapes and clusters play a part alongside genetic and other risk factors.
- False · It tumbles down the funnel trying shapes and keeping lower energy ones.
- False · The sequence holds the plan; chaperones only shield sticky patches.
- False · Boiling tangles white proteins into a mat that cannot untangle.
