Something that would appear in pairs on a DNA strand would be a base. The bases are made up of different parts:
A:Adenine
C:Cytosine
G:Guarnine
T:Thymine
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.
in DNA, each base pairs up with only one other base
The DNA molecule is composed of two DNA strands.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent

The replication is semiconservative. Each strand acts as a template for the synthesis of a new DNA molecule by the sequential addition of complementary base pairs, thereby generating a new DNA strand that is the complementary sequence to the parental DNA. Each daughter DNA molecule ends up with one of the original strands and one newly synthesized strand.
DNA polymerase is an enzyme which synthetizes complementary DNA strand, according to the template strand. So if you have a single-strand DNA, DNA polymerase can sit on it and synthetize the second strand, by the pairing rules - A pairs with T, G pairs with C.
The DNA molecule is composed of two DNA strands.
A DNA strand contains only 4 bases, which come in pairs. Adenine pairs up with Thymine, and Guanine pairs with Cytosine.
The complementary DNA strand is CGTTTGATGG. A pairs with T, and G pairs with C.
tgcagac. A pairs with T and C Pairs with G.
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.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
in DNA, each base pairs up with only one other base
You can predict the base seqences of a DNA molecule if you know what one strand is, because of double Stranded DNA. Each strand matches up with a letter and repeats a pattern throught the entire DNA strand.
