A modification in genetic material like DNA due to errors and mutating agents causes mutation that can lead to diseases and disorders.

The spontaneous mutation originates due to error in:

DNA Replication

Mutation can be explained as:

During the life cycle when the net outcome goes wrong with Deoxyribonucleic acid is called spontaneous mutation. An example of spontaneous mutation is sickle cell anaemia.When the nitrogenous base-pairing goes wrong during the replication of the parent DNA strand then spontaneous mutation can occur.Environmental factors like smoke and ultraviolet radiations or mistakes in DNA copying are the reason for spontaneous mutations.

Thus, errors in DNA replication can cause spontaneous mutation.

Replication

A spontaneous mutation usually originates as an error in replication

Explanation:

During DNA replication, the enzyme DNA polymerase help to proofread the template strand, however it is not always 100% accurate. Thus, base pairs could become mismatched resulting in spontaneous mutation

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
