The DNA formed by biochemical compounds (nucleotides) is organized in chromosomes, in all eukaryotic cells chromosomes are linear.
<h2>What is DNA?</h2>
DNA is the deoxyribonucleic acid responsible for containing the instructions that determine all the characteristics and functions of an organism.
<h3>Characteristics of DNA in eukaryotic cells</h3>
- Each DNA molecule is made up of two chains made up of a large number of biochemical compounds called nucleotides.
- Each nucleotide, in turn, is made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base.
- DNA takes the form of a double helix, where the sides are chains of sugars and phosphates connected by "rungs," which are the nitrogenous bases.
Therefore, we can conclude that in eukaryotic cells, the DNA is found in the nucleus, where the chromosomes reside, and in all eukaryotic cells the chromosomes are linear.
