Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

What is pharynx?</h3>
- A hollow tube called the pharynx extends from the back of the nose down the neck and finishes at the top of the trachea and esophagus.
- The nasopharynx, oropharynx, and hypopharynx are the three components of the pharynx.
- The pharynx, sometimes known as the throat, is a component of the digestive and respiratory systems.
- It transports food, liquid, and air from the mouth and nose downward.
- Common infections like tonsillitis and a sore throat can spread to the pharynx.
- The throat is a muscular tube that resembles a ring and serves as the conduit for liquids, food, and air.
- It connects the mouth and nose to the breathing passages and the esophagus and is situated behind the nose and mouth.
