What is the mutation caused by the addition of a nucleotide to an already existing gene sequence called? a. deletion b. duplication c. insertion d. inversion

An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated.

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
