Watson and Crick established that A (adenine) is always found opposite T (Thymine), and G (Guanine) is always opposite C (cytosine). A-T, G-C. Therefore, reading from left to right, the complementary strand would be T C A G.

If the sequence of bases in one DNA strand is TAG then the sequence of bases in the other strand will be?
The corresponding mRNA strand would be AUCG.
If the sequence of bases in one strand C-A-A-G-T what is the sequence of bases on the matching strand?
the complimentary styrand would be: T-C-C-G-A-T
Would the amount of cytosine and guanine be equal to each other in a RNA molecule?
The amounts of cytosine and guanine will not necessarily be equal to each other in a molecule of RNA. The concentration of cytosine (C) is equal to that of guanine (G) in molecules of DNA because DNA is a double helix. All the nitrogenous bases in one strand of DNA are paired with their complementary base in the other strand. As C and G are complementary bases, every time you find a C in one strand, the other strand will contain a G at the same location. Likewise, every time you find a G in one strand, the other will have a C. Therefore, the concentration of cytosine in a molecule of DNA will be exactly equal to that of guanine, assuming that there are no mismatch errors. RNA, however, is a single-stranded molecule. The bases in RNA are not paired with each other, so even between a set of complementary bases, there is no requirement that the concentrations be identical.
Why are two new strands of DNA exactly like the old strand?
The new strands have new complementary bases on one side and the other is made of the original strand. A strand of DNA has two strands that are complementary to each other in a double helix. When it gets copied one side is used as a template for the new side being added on, the bases cytosine and guanine match up and the bases adenine and thymine match up to each other. For example: If the original DNA strand has this order: 3' G-A-T-A-A-C-C 5' then the new complementary strand has: 5' C-T-A-T-T-G-G 3'
How does each nucleotide differ?
All nucleotides have a 5-carbon sugar, a phosphate group, and a nitrogenous base. The bases are the differences. There are four bases in DNA: adenine, thymine, cytocine, and guanine. In RNA, the base Uracil replaces thymine. Adenine on one strand will always pair with a thymine on the other, and vice versa, while a cytosine on one strand will always pair with a guanine on the other strand. In RNA adenine will always pair with a uracil, and there is no thymine.

What is a characteristic of nucleic acids in which the sequence of bases on one strand is paired to the sequence of bases on the other?
Complementary Base- pairs
Suppose 1 strand of a DNA molecule contained the following bases a c g t c t g what would be the bases on the other strand?
tgcagac. A pairs with T and C Pairs with G.
If the sequence of bases in one strand C-A-A-G-T what is the sequence of bases on the matching strand?
the complimentary styrand would be: T-C-C-G-A-T
What is in the bonding of nitrogenous bases?
The bases from one strand form hydrogen bonds with the bases on the other strand. Adenine forms two H-bonds with thymine. Cytosine forms three H-bonds with guanine.

Can a single DNA strand bond with another single DNA strand?
Yes this is true :) - This happens if the two strands of DNA have organic bases complimentary to one another - E.g if one strand has the Base code - TAACGATC the other strand would have the Base code - ATTGCTAG - this is because the bases pair up as so - Adenine&& Thymine and Cytosine and Guanine - this is bcause these organic bases are complimentary due to the molecular structures allowing certain number of hydrogen bonds to form between these bases - A & T have two hyrdrogen bonds and C& G have three :D xx
How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.

How does DNA copy of itself?
DNA makes copies of itself through the process of replication. Because the nucleotide bases are complementary, they automatically make the other strand of complementary bases when the division of the cell occurs.
What is the complementary strand of DNA?
Yes, strands of DNA are complementary. Complementary implies that a sequence of nucleotides (ex. ATATG) is ordered in a way that it directly corresponds to another sequence of nucleotides (ex. TATAC). Since DNA is double stranded in most circumstances, barring mutagenesis, one strand would be pair with its complementary strand, thus forming the double stand.
