Respuesta :
Cytosine, guanine, thymine and adenine are NOT referred to as phosphates (they are nitrogen bases), whereas DNA is in the shape of a double helix'.
- A nucleotide is made up of sugar, phosphate and a nitrogen base.
- The replication is performed after cell division.
- Adenine always pairs with thymine, whereas cytosine pairs with guanine.
- Complementary base pairing matches up nitrogen bases.
- The letters that make up the DNA molecule code for genes.
- Replication results in two strands of DNA, each of which has half of the original strand.
- Hydrogen bonds hold nitrogen bases together, forming the rings of the DNA ladder.
In conclusion, Cytosine, guanine, thymine and adenine are NOT referred to as phosphates (they are nitrogen bases), whereas DNA is in the shape of a double helix.
