What is redundancy in the genetic code? and why is it beneficial to organisms? i really need on this. any answers would be appreciated

"Each codon represents a single amino acid, though some amino acids have several different codons. There are 20 different amino acids in human proteins so some amino acids are encoded for by more than one codon (this is refered to redundancy of the genetic code)." according to (www.uvm.edu/~cgep/Education/GeneticCode.html) and "The genetic code allows an organism to translate the genetic information found in its chromosomes into usable proteins" according to (www.biologyreference.com › Fo-Gr)

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
