Where can circular DNA be found in animals?
Circular DNA can be found in animal cells within mitochondria and chloroplasts. Mitochondrial DNA is circular in structure and is separate from the nuclear DNA. Chloroplasts in plant cells also contain circular DNA.
Which one of the cells was studied first?
First observed cells were plant cells. Robert Hook observed cork cells.
What is a circular chromosome?
A circular chromosome is, essentially, exactly what it sounds like: a chromosome (strand of DNA that carries the genetic information of an organism) that is circular. Circular chromosomes are found in prokaryotes such as bacteria, as well as in mitochondria and chloroplasts. Eukaryotic cells, on the other hand, typically have chromosomes that are linear, meaning they have two ends that do not connect.
What parts of a plant cell were clearly visible in the onion root cells focused under HPO?
Under high power objective (HPO) microscopy, several parts of the onion root cells are clearly visible, including the cell wall, which provides structure; the large central vacuole, which stores nutrients and waste; and the nucleus, often seen as a darker circular structure within the cell. Additionally, the cytoplasm can be observed, which contains various organelles. The overall rectangular shape of the cells is also evident due to the rigidity of the cell walls.
What cells have prokaryotic cell structure?
Bacteria and archaea are the only types of cells that have prokaryotic cell structure. They lack a nucleus and organelles enclosed by membranes, and their genetic material is found in a single circular chromosome.
Where can circular DNA be found in animals?
Circular DNA can be found in animal cells within mitochondria and chloroplasts. Mitochondrial DNA is circular in structure and is separate from the nuclear DNA. Chloroplasts in plant cells also contain circular DNA.
The structure observed by Robert Hooke in plant cells was?
The structure observed by Robert Hooke in plant cells was a honeycomb-like structure that he named cells, which reminded him of small rooms in a monastery. This discovery led to the cell theory and revolutionized biology by establishing the fundamental unit of life.
When you examined the blood cells slide what parts are observed?
Most cells you see will be red blood cells (erythrocytes) and they lack a nucleus in their structure.
Do all cells have plasmid?
No. Plasmids are special circular DNA structure that is only found in prokaryotes.
Do eukaryote cells have plasmid?
No. Plasmids are special circular DNA structure that is only found in prokaryotes.
Do prokaryotic cells have circular DNA?
Yes, prokaryotic cells have circular DNA.
Who is the scientist that used his primitive microscope in 1665 to observe that plant materials have cellular structure?
The invention of the microscope allowed the first view of cells. English physicist and microscopist Robert Hooke (1635-1702) first described cells in 1665. ... of cork and likened the boxy partitions he observed to the cells (small rooms) in a ... plant cells and established the presence of cellular structures throughout the plant.
Is the DNA in prokaryotic cells circular or eukaryotic cells?
The DNA in prokaryotic cells is circular, while the DNA in eukaryotic cells is linear.
What is the shape of the cell of animal?
Animal cells are circular. Plant cells are rectangular.
What is the definition of circular DNA?
Circular DNA is a type of DNA molecule that forms a closed loop structure, as opposed to the linear structure found in most organisms. It is often found in prokaryotic cells such as bacteria and archaea, and can exist as plasmids or as part of the bacterial chromosome. Circular DNA is known for its stability and resistance to degradation.
What structure could be observed in cells in the low power field of a compound light microscope?
the nucleus, cell membrane, cytoplasm, and in plant cells, the cell wall and chlorplasts
Which one of the cells was studied first?
First observed cells were plant cells. Robert Hook observed cork cells.
