Question: What do all eukaryotes have that prokaryotes do not have? a. cell membrane b. nucleus c. DNA d. cytoskeleton e. flagella Cell Membrane: The cell membrane is a critical component of the cell as it allows for selective diffusion of compou...
How do bacterial flagella propel the cell? What structure in the cell has the 9+2 configuration? (a) Flagella (b) Spindles (c) Intermediate fibers (d) Both (a) and (b) (e) (a), (b), and (c). Prokaryotic and eukaryotic cells generally have which ...
In general, prokaryote reproduction works in a simpler manner than the reproductive methods of eukaryotic organisms. The process is a kind of cell division calledbinary fission, and it is basically a self-replication procedure. Intheory, the end result is two identical prokaryotic cells, and that...
Question: What is the role of the nucleus in cell division? The Nucleus: 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...
asymbioticrelationship. In particular, the engulfed cell began to function as an organelle within the larger eukaryotic cell that consumed it. Both chloroplasts and mitochondria, which exist in modern eukaryotic cells and still retain their own genomes, are thought to have arisen in this manner (...
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...
All eukaryotic cells secrete, and take up, exosomes. These tiny extracellular vesicles (EVs) are laden with genetic instructions that influence recipient cells, sometimes subtly, sometimes dramatically. Over the last 2 decades, scientific attention to exosomes has exploded: the number of annual citatio...
2A). All the eukaryotic Gcn5 homologues contain an acetyl transferase (AT) domain and a C-terminal bromodomain [33]. Bromodomains are approximately 110-amino-acid motifs found in many chromatin-associated proteins. Structural analysis revealed that the bromodomains of Gcn5 or PCAF have a ...
Various types of cells perform different functions. Based on cellular structure, there are two types of cells: Prokaryotes Eukaryotes Explore: Difference Between Prokaryotic and Eukaryotic Cells Prokaryotic Cells Main article: Prokaryotic Cells Prokaryotic cells have no nucleus. Instead, some prokaryotes ...
How do prokaryotic cells differ in size from eukaryotic cells? What do all eukaryotes have that prokaryotes do not have? a. cell membrane b. nucleus c. DNA d. cytoskeleton e. flagella Describe different components of prokaryotic and eukaryotic cells. Which of these are in animal ...
