Gold is used in DNA strands to study genetic material and in precision thermometers. It also unites complex chemical agents like proteins to create complex drugs. Gold contacts and sensors are used in car airbags due to gold's resistance to heat, humidity, and corrosion to ensure the airbags work when needed.

2. It is used in DNA strands to study the
genetic material of cells and is present
in precision thermometers and in the
union of complex chemical agents (such
as proteins) for the creation of highly
complex drugs and medicines.

3. For having a high
resistance to chemical
alteration by heat,
humidity and most
corrosive agents, the
airbags of cars have gold
contacts and electronic
sensors to ensure that
they work when it is
necessary.
