In drawings of DNA the lines connecting the two strands represent base pairings. DNA is made up of four base pairs. These four pair up A-T and C-G exclusively.

How many strands DNA strands does HPV have?
2 strands in total I believe.
What is the structure of DNA and nucleotide?
A DNA nucleotide is composed of the 5-carbon sugar deoxyribose, a phosphate group, and one of four nitrogen bases; adenine (A), thymine (T), cytosine (C), and quanine (G). A molecule of DNA is composed of two strands of nucleotides. The nucleotide strands are oriented such that the sugar and phosphate groups alternate down the outside of the strand, and the nitrogen bases are oriented toward the center of the two strands. In a DNA molecule, the two strands of nucleotides pair according to the base-pairing rule, which states that adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G). The nitrogen bases of the complimentary strands of DNA are held together by hydrogen bonds. Because of the 3-D structure of the nucleotides, the two DNA strands twist into a double helix, often likened to a twisted ladder. Refer to related links for illustrations.
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
What links together to form strands of dna?
a nucleotide
How many strands of nucleotides are in DNA?
Thousands upon thousands. Because DNA must contain all the characteristics of your being, it must be long.

Do hydrogen bonds hold two DNA strands together?
Either two or three, depending on the exact nucleotide. Three in G-C, two in A-T.
