Immunofluorescence studies on cells revealed that several of these actin-form specific mAb labeled actin-containing structures predominantly residing in either the cytoplasm or the nucleus. Taken together, our results suggest that oligomeric and/or polymeric actin forms exist in the nucleus that clearly ...
The nucleus contains the chromosomes that are the thread-like structures containing the genetic material (DNA) and the proteins (histone). It also...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can...
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-). It is the number of protons that determines the atomic number, e.g., H...
Cellular Structures and Organelles DNA and RNA Quantitation DNA and RNA Nucleic Acids Nucleus Physiological Probes Answer The three main types ofDNAinclude: A-DNA, B-DNA, and Z-DNA. The structure of A-DNA is a right-handed double helix (similar to B-DNA structure). The dehydrated DNA takes...
If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus. DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a ...

Gametes are haploid, which means they each have only one copy of the 23 chromosomes that make up the human genome. (The word “haploid”comes to us from the ancient Greekhaploos, or “single, simple, once”.) When the haploid egg and sperm cells unite, they eventually create a person ...
DNA and RNA production, cell growth and cell regeneration. They send messages to the nucleus and other structures in the cell which modifies cellular activities. The ability of cells to correctly “hear” these messages determines how well our bodies grow, repair themselves and fight off infection...
