Why are guanine and cytosine and they and adenine useful in the DNA molecules?

Guanine is a purine and Cytosine is a pyrimidine. They are nucleotides that pair together. The two are useful in DNA molecules because they pair together, along with Adenine and Thymine, which build a double helix. Guanine, Adenine, Thymine, and Cytosine are all nitrogenous bases.

Which four nitrogenous bases are purines?
There are four nitrogenous bases. A, C, T and G A and G are Purines C and T are Pyrimidines. a useful rhyme to remember this is " Silver is PURe AG" - silver is abbreiviated to AG in the periodic table
Does DNA or RNA have uracil?
purine. I remember cytosine, guamine, and uracil are pyrimindine because the word pyrimidine makes me think of the word pryamid and there are THREE pyrimidines which spell the word CUT :) hope that helps :)
What does a DNA nucleotide consist of?
deoxyribose sugars, which are bonded to a phosphate group and a nitrogenous base Very useful little critters, they are basically a nitrogenous base, a five-carbon sugar, and one to three phosphate groups (mono- to tri-phosphate). A very good article in the link below.
Why is hydrocarbon important?
it makes smaller molecules which is more useful.
How phosphorus is useful?
Metabolic molecules (ATP) Structure (phospholipids)
Why is cracking useful?
cracking is useful because large hydrocarbon molecules are broken into smaller ones. And these are needed for petrol and are more reactive.
What structure do mollusks use to extract useful molecules from coelomic fluid?
nephridia
Why is changing dodecane into smaller molecules useful?
because hydrogen molecules react with oxygen molecules which creates carbon dioxide which isn't good for the environment.
Why are cracking large hydrocarbon molecules more useful than the original large molecules?
There is more demand for smaller molecules because they can make up more fuels and plastics. There is less demand for the larger molecules.
When water and useful molecules are drawn back into the blood due to osmotic pressure?
Glomerular Filtration
What are small organelles filled with enzymes that break down large molecules and organelles that are no longer useful?
Lysosome
When water and useful molecules are drawn back into the blood due to osmotic pressure it is called?
Glomerular Filtration
