They're called Enzyme. They're made up of proteins. They act as a biological catalysts that can speed up chemical reaction. They have an active site that certain substrates binds into it and form a product. Enzyme works under optimum pH and temperature and the active sites are not changed unless denatured.

Frameshift mutation is caused by the addition or deletion of a base pair in the DNA of a gene.
Explanation:
Frameshift mutation also known as a framing error or a reading frame shift.
Frameshift mutations are due to either insertions or deletions of nucleotides. This causes the entire DNA strand to elongate or to shrink in size.
There are two types of frameshift mutations.They are insertions and deletions. Insertions involve the insertion of one of more extra nucleotides into a DNA chain.
Several diseases have frameshift mutations like HIV, Crohn's disease, cystic fibrosis etc.
