Phosphorus is the element found in nucleic acids but not in proteins.
<h2>Further Explanation
</h2><h3>Proteins </h3>
- Proteins are one of the major biomolecules that exists in nature.
- They are made of amino acids which are the building blocks. Amino acids contain four different elements which include;
- Hydrogen
- Oxygen
- Nitrogen
- Carbon
- Some amino acid contains sulfur element.
<h3>Nucleic acids</h3>
- Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
- The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.
<h3>DNA </h3>
- DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
- It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
- Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
- Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
- DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.
<h3>RNA
</h3>
- Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
- Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
- Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.
