Answer:
Summary
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
Prokaryotic cells lack a nucleus and membrane-bound structures.
Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
Explanation:
Eukaryotic Cells
Eukaryotic cells usually have multiple chromosomes, composed of DNA and protein. Some eukaryotic species have just a few chromosomes, others have close to 100 or more. These chromosomes are protected within the nucleus. In addition to a nucleus, eukaryotic cells include other membrane-bound structures called organelles. Organelles allow eukaryotic cells to be more specialized than prokaryotic cells. below are the organelles of eukaryotic cells , including the mitochondria, endoplasmic reticulum, and Golgi apparatus.
Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself. The DNA is located in the main part of the cell.
The looping of DNA around histone proteins... a. Produces the characteristic helix shape of the DNA b. Allow the room for cellular machinery to reach all genes so they may be transcribed c. Compacts the DNA allowing a large amount of DNA to fit into the cell d. PreventS the DNA from becoming kinked and breaking e.
The study of heredity which is a biological process where a parent passes certain genes (traits) onto their offspring. <span>Heredity is the process that makes variations between individuals causing the evolution of species by natural selection. Inherited traits are controlled by one or more genes The study of heredity in biology is genetics.</span>
Answer:
The neutrophil forms multiple lamellipodia extensions
Explanation:
Neutrophils are white blood cells (granulocytes) which comprise the first line of defense in the innate immune system. The lamellipodium (in plural, lamellipodia) is a cytoskeletal actin extension found in mobile cells, whose main functions are cell motility and migration. Rac1 is a member of the Rho GTPase protein family which is involved in actin-myosin cytoskeletal reorganization of neutrophil cells in response to microorganism infections. In this regard, it has been shown that Rac1 controls the initial uncapping of actin ends in order to regulate cytoskeleton dynamics, thus regulating lamellipodia formation. By using mice as models, researchers observed that Rac1 constitutive activation may lead to the formation of multiple lamellipodia in neutrophils.
