Dna is a nucleic acid polymer composed of which repeating structural unit? nucleotides phosphate groups ribosomes proteins

The answer is nucleotides.DNA is a nucleic acid (desoxirribunocleic acid) polymer composed of units, this is monomers, named nucletoids. Nucleotids are organic molecules with several functional groups ( phosphates, OH, NH2). The monomers bond each other to form a large chain (a polymer) which is the DNA.

The answer would be interphase.

Molecules called lipids have long hydrocarbon chains that determine the way they act. they can be fats, oils, or hormones, and even exist in our cell membranes
