Operon: Tryptophan Operon

Tryptophan Operon

The trp operon is another well-known example of gene regulation in bacteria, particularly in Escherichia coli (E. coli). This operon is involved in the synthesis of the amino acid tryptophan, an essential component of proteins. The trp operon՚s function is to regulate the production of enzymes necessary for tryptophan biosynthesis based on the availability of tryptophan in the environment.

Unique and Repetitive DNA

Concept of Unique or Non-Repetitive DNA

• Unique DNA, also known as non-repetitive DNA or single-copy DNA, refers to sequences in the genome that exist in only one or a few copies. These sequences typically encode functional genes or regulatory elements that are essential for the organism՚s development, growth, and function. Unique DNA makes up a significant portion of the genome and includes coding regions for proteins, as well as non-coding regions with regulatory function…
