Answer:
double helix
Explanation:
Deoxyribonucleic acid, commonly known as DNA, consists of two long polynucleotide chains composed of four types of nucleotide subunits i.e. A, G, C, T. Each chain is called a strand. Each nucleotide is made up of a pentose sugar, phosphate group and a nitrogenous base.
DNA is a double-helical structure that contains each strand in a spiral or coiled form. This double helix structure forms when two complementary strands are held together by hydrogen bonds. The bonding occurs between the nucleotide base portions of the complementary strands e.g G-C, A-T.

The answer is C your welcome (:
Genes have different variants, called alleles. Each individual possesses two alleles for each gene (one inherited from its father, and one from the individual's mother). Alleles can have different relations with each other, and some alleles have a stronger expression, dominating the determination of the trait in the individual.
In the case of codominance, both of the alleles are equally influential, so both of them are expressed in the individual.
The most famous example of codominance is in the A,B,O blood type alleles.
The A and B alleles are codominant, so when both of them are present in the individual, that individual expresses both A and B proteins, resulting in AB blood type.
