Why have no operons been found in eukaryotic cells?
Operons are not common in eukaryotic cells because eukaryotic genes are typically regulated individually by diverse mechanisms such as transcription factors, enhancers, and silencers. Eukaryotic gene expression is more complex and often involves tissue-specific regulation, post-transcriptional modifications, and chromatin remodeling, which are not typical features of prokaryotic operons.
Are microtubules found in eukaryotic cells or prokaryotic cells?
Microtubules are found in Eukarytotic cells. However, some archeabacteria have been found to contain microtubule-like structures but these are not true microtubules.
What is the largest Amoeba ever found?
The largest amoeba species is the Gromia sphaerica, where individual cells have been found to reach sizes of up to 4 centimeters in diameter.
HeLa cells have been used in research to?
HeLa cells have been used in research to study cell biology, cancer, virology, and genetics. These cells have been instrumental in advancing our understanding of diseases and developing new treatments and therapies.
Do protists have genetic material?
yes, DNA is found in the Nucleoid Region, then there are Plasmids, which also contain genetic material.

What parts of the body have adult stem cells been located?
Adult stem cells have been found in the brain, the bone marrow, and in peripheral blood. They have also been found in skeletal muscle, teeth, and the heart.
What is the largest Amoeba ever found?
The largest amoeba species is the Gromia sphaerica, where individual cells have been found to reach sizes of up to 4 centimeters in diameter.
Are animal cells unicellular?
i do not think so, every website i have been to, they do not seem to be unicellular, otherwise multicellular, but that's just what i found
How long had Henrietta been dead when her family found out that her cells were still alive?
Henrietta Lacks passed away on October 4, 1951, and her family discovered that her cells, known as HeLa cells, were still alive in 1975. This means she had been dead for nearly 24 years when they learned about the existence of her immortal cells. The revelation came as a shock to her family, as they were unaware of the use of her cells for scientific research.
At the end of meosis cells have been produced by one cell how many cells have been produced?
4 cells have been produced at the end of meiosis
Where in the human body would you find cells with a large number of mitochondria?
Cells with a large number of mitochondria are commonly found in tissues with high energy demands, such as muscle cells and liver cells. These organelles play a crucial role in producing energy for these cells through aerobic respiration.
What color is the lysosome in the plant cell?
Lysosomes are rarer than hens teeth in plant cells, so I would not know what color they would be when found. The " digestive " action preformed by lysosomes in animal cells is usually preformed in the large central vacuole of plant cells. Lysosomes in plant cells is still highly debated, but some seem to have been found. You will not find much at Google on this, but you can try to find something.
What is the structure not found in all cells?
Nucleus is NOT found ALL cells.Common features of cells include the cell membrane, the cytoplasm, and the cytoskeleton. Cells also have ribosomes, which are structures where proteins are made. . Cells are classified as prokaryotes or eukaryotes.The smallest and simplest cells are prokaryotes. A prokaryotic cell is a cell that lacks a nucleus and other internal compartments. As a group they are also among the most ancient. Fossilized prokaryotic cells have been found in rocks over 3 billion years old. A eukaryote is a cell that has a nucleus and other internal compartments, known as organelles.
What structure is missing from platelets that is found in most other living cells?
Different from other cells the Platelets do not have a cytoplasm, this has been sientificially proven by Dr James Macaroy at the oxford university in the human body category, it also has been proven by several other education websites for children at school.
How was reproduction explained before cells?
there is no such ting as before cells there has always been cells in the body
