Mutations will result in the transcription and translation of proteins with possibly the wrong amino acids. In some cases, you can completely inactivate the usefullness of the protein by changing just one nucleotide.
It's like throwing a bunch of screwdrivers and wrenches into an assembly line.

An organism is an whole. When you have mutations a bad protein is formed with a great probability snd this is harmful since that bad protein takes the place of a useful protein

Because DNA codes for proteins which are the building blocks of organisms, enzymes, chemical messengers...if the DNA code changes (mutates) then those mutated genes can no longer code for the correct protein and thus...the organism can no longer produce cells, repair damage, etc...

Imagine a smooth-running Mercedes engine. A huge number of finely crafted parts working in harmony. Now replace a piston rod with a random tree branch or a blender. Nothing good is going to happen.

Because they seldom grow at a regulated or predictable pace, thereby overtaking the organism itself such as cancer.
