does eukaryotic cells have restriction enzymes?
314931
Answer and Explanation: Eukaryotic cells do not have restriction enzymes; this is because eukaryotic DNA is highly methylated and restriction enzymes would not work on it.

Following are the substantial difference between Prokaryotic Cells and Eukaryotic Cell: ... Organelles like mitochondria, ribosomes, Golgi body, endoplasmic reticulum, cell wall, chloroplast, etc. are absent in prokaryotic cells, while these organelles are found in eukaryotic organisms.

However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) several rod-shaped chromosomes.

Nucleus/DNA: Eukaryotic cells have a nucleus surrounded by a nuclear envelope that consists of two lipid membranes, according to Nature Education. The nucleus holds the eukaryotic cell's DNA.

Eukaryotes and prokaryotes both have DNA, but it is only enclosed in a membrane in eukaryotic cells. ... In general, prokaryotic cells do not have a true nucleus or membrane-bound organelles, whereas eukaryotic cells contain both a nucleus and organelles enclosed by membranes.

Restriction enzymes are DNA-cutting enzymes found in bacteria (and harvested from them for use). ... Many DNA-digesting enzymes (like those in your pancreatic fluid) can do this, but most of them are no use for sequence work because they cut each molecule randomly.

Eukaryotic cells are generally bigger than prokaryotic cells. This allows eukaryotes to have organelles, have slower turnover rates of macromolecules, and requires the presence of mechanisms to move things around the cell.

Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. ... Prokaryotes, on the other hand, have no membrane-bound organelles.

Eukaryotic cells have a nuclear envelope which surrounds the genetic material to form a nucleus and separates the DNA from the other cellular content. Eukaryotic cells also have DNA in tightly bound forms with histones called chromatid. Genes in prokaryotic cells a on a single circular molecule of DNA.

Eukaryotic cells are found in higher organisms such as animals, plants, fungi such as moulds and yeasts. They are characterised by having true nucleus surrounded by a nuclear membrane, they also possess mitochondria responsible for producing the energy needed for cell growth and repair.

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
759284
Among eukaryotes, the chromosomes are contained in a membrane-bound cell nucleus. The chromosomes of a eukaryotic cell consist primarily of DNA attached to a protein core. They also contain RNA.

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis. ... In eukaryotes, chromosomes are linear structures.

Prokaryotic cells are simple cells that lack membrane-bound nuclei and complex organelles. Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes. Prokaryotes do, however, contain ribosomes, though smaller than the ribosomes in eukaryotic cells.

Introduction. Restriction enzymes are also called 'molecular scissors' as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.
187867
They reproduce using a process called binary fission. ... Eukaryotic cells feature a cell cycle and reproduce sexually using the processes of mitosis and cytokinesis. A few exceptions to the "only prokaryotes undergo binary fission" rule, however, do exist.

Justify your answer. No, eukaryotic cells do not have restriction endonucleases. ... Methylation protects the DNA from the activity of restriction enzymes . These enzymes are present in prokaryotic cells where they help prevent the invasion of DNA by virus.
