The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.

Every slice of the bread, contains a number of blister like pores. These blister like pores suggests that the air or some gas might be present there. In case, the bread has no air, the surface of the bread must be smooth rather than rough.
The bread is formed by the fermentation of the sugar molecules present in the dough with the help of yeast. These blisters like structure on the bread is present due to the gas produced during fermentation.
Answer:
Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
