Uracil. It's a nucleotide but it's found in RNA only.
The four bases of a DNA molecule are called adenine, thymine, cytosine, and guanine.
The DNA molecule is known to break the rungs apart. In order for this to be accomplished, the bases must synthesize with the DNA.
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.
its 4
No. Mutation changes the sequence of nitrogen bases in a DNA molecule.
nitrogeous bases
AT and GC
The DNA molecule is composed of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). These nucleotides join together in a specific sequence to form the double helix structure of the DNA molecule.
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
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.
If the spiral molecule is DNA then the four bases are Adenine, Thymine, Cytosine and Guanine.
There are four types of bases in DNA: adenine, cytosine, guanine, and thymine. However, a molecule of DNA may be a polymer of millions of these bases in a specific arrangment.
