Zooflagellate is a free living protozoan with a whip like appendage. It is non-photosynthetic and feed on decaying organic matter. Euglena is a single cell flagellate eurkaryote, which has features of both plant and animal. Two organelles that are present in euglena but which are not present in zooflagellate are chloroplast and photoreceptors.

Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.
<h3>How many genes are there in an operon?</h3>
Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).
<h3>Yes, there is just one promoter for operons.</h3>
An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.
<h3>The promoter is a 3 or a 5?</h3>
An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
