phosphodiester linkage
the red dotted lines represent covalent bonds
its nucleic acid monomer
its nucleic acid polymer
the red dotted lines represent hydrogen bonds
it is dna
it is rna

Explanation:

1. The red - dotted lines in nucleic acids are hydrogen bonds, not covalent bonds. Covalent bonds are the stronger bonds like the phosphodiester linkages shown.
2. The structure is a nucleic - acid polymer as it is composed of multiple nucleotides linked by phosphodiester bonds. A monomer would be a single nucleotide unit.
3. The presence of thymine (T) indicates that it is DNA, not RNA (RNA has uracil instead of thymine).

Answer:

• its nucleic acid polymer
• The red dotted lines represent hydrogen bonds
• It is DNA
