Cells With & Without a Nucleus | Types & Structure from Chapter 8 / Lesson 29 75K Learn about cells and the cell nucleus in the body of a living organism. Understand the classification of cells as prokaryotic cells (cells that lack a nucleus) and eukaryotic cells (cells that contain ...
Answer to: In what two ways do eukaryotic cells overcome some of the limitations on cell size to allow them to be larger than prokaryotic cells? By...
Transfection is when eukaryotic cells take up foreign DNA or RNA by non-viral means. Mammalian and many other eukaryotic cells do not naturally take up foreign nucleic acids, but scientists have discovered ways to introduce plasmid and other foreign DNA or RNA into eukaryotic cells. Much like th...
In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
01_02_Numbers of nuclei in cells 15 related questions found What is an example of a Multinucleate? Multinucleate cells (multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. ... For example,slime...
Although all eukaryotic cells have a number of elements in common, they vary widely in appearance and function depending on the tissue to which they contribute. This is perhaps more true of nerve cells than of any other cell in the human body, as these cells have unique shapes, interactions...
Prokaryotic and Eukaryotic Cells Written by tutor Anneliese A. Prokaryotic cells evolved before eukaryotic cells (“pro” comes from the Greek word for
The redox activity was significantly different in the cells culture medium vs the presence of eukaryotic cells (p < 0.001). The ability to β-galactosidase production was different for selected strains: Bifidobacterium longum ssp. longum indicated 91.5% of positive cells, whereas Bifidobacterium ...
In biology, vesicles and vacuoles are subcomponents present within cells. They both contain liquid within a membrane consisting of a layer of lipids. Answer and Explanation: Both vesicles and vacuoles provide an environment separate from the rest of the cell. A vacuole is equivalent to a number...
What is the role of peroxisomes in eukaryotic cells? Peroxisome, membrane-bound organelle occurring in the cytoplasm of eukaryotic cells. ... Peroxisomes containenzymes that oxidize certain molecules normally found in the cell, notably fatty acids and amino acids. Those oxidation reactions produce hydr...
