"DNA is essentially made up of a sequence of nucleotides, each of which are associated with one molecule of phosphate."
This is true, however not completely. Let's look at an example. Say we have a DNA molecule that is 10 base pairs long ( double stranded, so actually has 20 bases).
The statement suggests we would have 20 phosphates in this molecule of DNA. However, we actually have 24. This is because the nucleotides situated at the 5' terminals of each strand have 3 phosphates rather than one. Since we have 2 5' terminals we have an excess of 4 phosphates which we did not account earlier, so instead of 20, we are now at 24 phosphates.
What else can I help you with?
Does RNA contain a phosphate group like DNA?
Yes, RNA contains a phosphate group in its backbone, just like DNA. The phosphate group is important for forming the sugar-phosphate backbone that gives RNA its structure and stability.
What electric charge do the phosphate groups in DNA have?
A negative charge, as do all phosphate groups.
Does DNA have oxygen?
Yes, DNA is made of hydrogen, oxygen, carbon, nitrogen, and phosphorus.
What contains phosphate DNA or RNA?
Both ! Both are made of nucleotides : phosphate-ribose-nucleic acid. The strands are made by the linkage of phosphates on riboses : P-ribose-P-ribose-P-ribose-P-ribose-etc. The difference between DNA and RNA is that the ribose molecule is dehydrated (DNA) or not (RNA). DNA means DeoxyriboNucleic Acid RNA means RiboNucleic Acid
In DNA what do phosphate groups bond to?
Phosphate groups in DNA bond to sugar molecules through a phosphodiester bond to form the backbone of the DNA strand.
Is a phosphate DNA or RNA?
Both DNA and RNA contain a sugar phosphate group as the backbone to their structure. In DNA the sugar is deoxyribose, where as in RNA it is just ribose.
Does RNA contain a phosphate group like DNA?
Yes, RNA contains a phosphate group in its backbone, just like DNA. The phosphate group is important for forming the sugar-phosphate backbone that gives RNA its structure and stability.
What electric charge do the phosphate groups in DNA have?
A negative charge, as do all phosphate groups.
DNA and RNA are made up of nuceotides which contain what?
A sugar, a base, and a phosphate group.
Why is DNA negatively charged?
DNA is negatively charged because of the phosphate group that is in each nucleotide. DNA also has a negative charge because of the phosphate icons in its chemical "backbone".
Does DNA have oxygen?
Yes, DNA is made of hydrogen, oxygen, carbon, nitrogen, and phosphorus.
How much phosphate molecules are inside the DNA?
There are an estimated 3 billion base pairs inside of human DNA. Each base contains one phosphate group so each base pair would contain two. Ergo, there would be an estimated 6 billion phosphate groups in human DNA.
3 parts of DNA nucleotides?
Sugar: DNA nucleotides contain a sugar molecule called deoxyribose. Phosphate: Each DNA nucleotide has a phosphate group attached to the sugar molecule. Nitrogenous base: DNA nucleotides contain one of four nitrogenous bases - adenine (A), thymine (T), cytosine (C), or guanine (G).
A DNA nucleotide does not contain?
A nucleotide does not contain an organic acid.A nucleotide is similar to a nucleoside but does not contain a polymerase.
Is deoxyribose and uracil found in a DNA nucleotide?
No. Deoxyribose is the sugar in a DNA nucleotide. A DNA nucleotide would also include a phosphate group and a nitrogen base.
What three combinations of substances do individual nucleotides of DNA contain?
A purine or pyrimidine base;A sugar;A phosphate group.
Do nucleic acids contain phosphates?
Yes, nucleic acids such as DNA and RNA contain phosphate groups in their backbone. Phosphate groups link the sugar molecules in nucleic acids, forming the characteristic backbone structure.
