What are the nitrogen based pairs?
The nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. They pair with each other as follows: adenine pairs with thymine, and cytosine pairs with guanine. The nitrogen bases in RNA are adenine, guanine, cytosine, and uracil. They pair with each other as follows: adenine pairs with uracil, and cytosine pairs with guanine.
What breaks the bonds between the nitrogen bases of the DNA molecule?
Your answer is "Helicase". This is the enzyme responsible for the unzipping of the DNA molecule, or in other words, the breakage of the bonds of its nitrogen bases.
Where in the DNA molecule does hydrogen bonding occur?
between the nitrogen bases of the two strands of DNA
What is nitrogen bases role in DNA?
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
What kind of nitrogen-containing bases does DNA contain?
Adenine, Guamine, Thymine and Cytosine
Describe how each of the DNA nitrogen bases together in DNA?
Describe how each of the DNA nitrogen bases pair together
Which pair of nitrogen bases will form a bond in a DNA molecule?
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
Expain how the nitrogen bases of the DNA ladder pair up?
simple adenine pairs with thymine and guanine pair with cystosine.
How the nitrogen bases pair in a DNA molecules?
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
What are the 4 DNA nitrogen bases pairing rules?
The 4 Nitrogen Bases are Adenine, Guanine, Cytosine and Thymine
Two or four nitrogen bases linked together in each double standoff DNA?
Base pair
What occures when 2 strands unzip and the nitrogen bases pair with different nitrogen bases?
This is the process of DNA replication. A DNA strand in the nucleus of a cell, starts off by being "unzipped" by helicase (an enzyme). Then another enzyme, DNA polymerase matches the nitrogen bases (which are freely floating in the nucleus), of each half with their matches, this forms two identical strands, of DNA.
What are the two nitrogen bases from DNA that link together?
Guanine and Cytosine pair with each other and Adenine and Thymine pair with each other.
What does Nitrogen bases floating in the nucleus pair up with on each half of the DNA molecule?
When a nitrogen bases floating in the nucleus ipair up with the basis on each half of the DNA molecule. Remember that the pairing of bases follows definite rules: A always pairs with T, while G always pairs with C. Once the two new bases are attached, two new DNA are formed.

What rungs of DNA ladder made up of?
The rungs of DNA are made up of the nitrogenous bases Adenine (A), Cytosine (C), Guanine (G) and Thymine (T). Each rung represents the bonding of two bases (one from each DNA strand). A binds with T and C binds with G.
A pair of these form a rung in the DNA ladder?
A pair of the 4 nitrogen bases represented by an a, t, c, or g
What is the process in which DNA nitrogen bases are turned into RNA nitrogen bases?
transcription
