We can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.
<h3>What is a gene?</h3>
To expand on the definition given, we can say that a gene is, as mentioned, a series of base pairs known as nucleotides that will code for RNA. The RNA in question is messenger RNA that will later become a protein. Through this process, genes code for every aspect of an organism and will determine its morphology and all other biological aspects.
Therefore, we can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.
Euglena are a unicellular organism. They are classified into the Kingdom Protista. They are then further classified into the Phylum<span> Euglenophyta. All euglena can make their own food by photosynthesis.</span>
