Hydrogen bonds
In a DNA molecule, two polynucleotide strands are present. These strands are arranged in a double helix structure, with each strand consisting of a sequence of nucleotides that are complementary to each other.
each strand in the DNA molecule has a gap of 3.4 angstrom(Ao) between them. the total length of one series of strand or 1 DNA molecule is 34 Ao. therefore 34/3.4=10. there are 10 strands or N2 base pairs in a DNA molecule.
The DNA molecule is composed of two DNA strands.
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
The two strands of nucleotides in a DNA molecule run in opposite directions, referred to as antiparallel. This means that one strand runs in a 5' to 3' direction while the other runs in a 3' to 5' direction. This arrangement is essential for DNA replication and other cellular processes.

The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.

Strands within a molecule can bond to each other through interactions such as hydrogen bonding, Van der Waals forces, or hydrophobic interactions. These bonds occur due to the chemical properties of the molecules involved and help stabilize the overall structure of the molecule.

No, the two strands of DNA are not identical to each other. They are complementary and have opposite sequences of nucleotide bases.
There are two strands of DNA in a DNA double helix, each consisting of many nucleotide subunits. They are like building blocks that make up the DNA molecule, which would then be like a block tower. A 'strand of nucleotides' as you put it would basically be a DNA molecule (if they are deoxyribose nucleotides) or if they are ribose nucleotides, they would be a RNA molecule. DNA can come in double stranded helices (most of the time) or can be single stranded (as in some viruses).
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
As the strands are in contact with each other, of course there is.
