Do bacteria cells have a nucleus?

Yes they do because a nucleus is the control center of all unicellular organisms and multicellular organisms.

No they don't, they are prokaryotes which means they have no nucleus or membranous structure in their cytoplasm.

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
