A gene is a specific portion on the DNA that code for a functional protein. i.e DNA consists of several genes, and some non-coding sequences that are usually spliced off during post-translational modification.
In other words, a gene can be best described as each single, meaningful sentence in the instruction book for building an organism.

Bacteria and archaea are the two types of living beings made up of prokaryotic cells.
<h3>What are bacteria and archaea?</h3>
Bacteria and archaea are both prokaryotic and unicellular organisms. This means that they both lack a true nucleus and membrane-bound organelles. The genetic material is present in a long single loop of chromosome, called the nucleoid.
Both bacteria and archaea have a cell wall present outside of the cell membrane. The structural composition of the cell wall is different among them. In bacteria, the cell wall is made up of peptidoglycan (a sugar and protein complex compound) and in archaea, it is made of pure polysaccharides.
Both of these organisms reproduce asexually. They also have flagella for locomotion, pilus for adherence and a capsule outside of the cell wall for protection against conditions like dehydration.
Therefore, bacteria and archaea are living beings made up of prokaryotic cells.
