Biology, Eighth Edition (Raven) Eukaryotic DNA is packaged into chromosomes. Chromosomes are single strands of DNA. Bacterial DNA is packaged into a single chromosome that is a continuous loop. In both cases, the DNA must be folded or coiled so that it will fit into the cell.In bacteria the compaction involves DNA binding proteins that help to form initial loops followed by coiling of DNA.acterial DNA is packaged into a single chromosome that is a continuous loop.

Because they are also so small, it is easier to get the necessary products of photosynthesis and respiration to all parts of the (one-celled) organism, than it is in eukaryotes.osted on. (Answer #1).

DNA Organization in Prokaryotes and Eukaryotes Deoxyribosenucleic acid, as you know in humans and in other eukaryotic organisms codes our chromosomes and makes us the way we are! Similarly, in prokaryotes, like bacteria, DNA makes up their genetic code or in other words what they are. This includes their function and their appearance. Universally, DNA contains purines (adenosine, guanine) and pyrimidines (cysteine, thymine, uracil (found in RNA)).

Do Bacteria Cells Have DNA? DNA In Bacteria. Prokaryotic cells contain DNA that is, as you probably guessed, much simpler than that of our own cells. DNA found in eukaryotes is a complex twisted double helix molecule full of genes that determine everything about a living thing.

- So they came in with their own DNA, and now they still have some of their own DNA that carries the code for some of their own proteins. They also need some proteins coded by genes in the nuclear DNA. A woman scientist first suggested all this, Lynn Margulis.he best story we have now is that mitochondria are actually the descendants of bacteria that hitched a ride in larger, more complex cells. Our cells, and those of plants, amoeba-type things, and fungi, are eukaryotic..

Farthest Planet from the Sun Farthest Planet from the Sun. Like many planets, Neptune’s orbit isn’t exactly circular. Instead, Neptune orbits the Sun in an elliptical orbit. At its closest point, Neptune gets within 4.45 billion km, and then orbits out to a distance of 4.55 billion km. It takes almost 165 years to complete one orbit around the Sun.

- Prokaryotic and eukaryotic cells differ a great detail in both the amount and the organization of their molecules of DNA. a. Eukaryotic cells contain much more DNA than do bacteria, and this DNA is organized as multiple chromosomes located within a nucleus.b. The nucleus (def) in eukaryotic cells is separated from the cytoplasm by a nuclear envelope (nuclear membrane) (see Fig.32).rokaryotic and eukaryotic cells differ a great detail in both the amount and the organization of their molecules of DNA. a.

More on Characteristics of Bacteria... Bacteria are prokaryotes, i.e. they do not have their DNA enclosed in a nucleus (Bacteria, 2005). They are among the earliest life forms that appeared on Earth billions of years ago, and helped change the environment, creating oxygen which enabled higher forms to evolve.

What is a pit file and how do I open a pit file? The PIT extension is one of the original Macintosh file compression formats. It has become obsolete, and is replaced by more advanced compression algorithms, such as Zip and Stuffit. PIT files are categorized as compressed files and are known as PackIt Compressed Archives as they are mostly used by MAC OS PackIt tool. However, even if PIT files are very useful especially when it comes to PackIt compression, these files are also obsolete files already.

Bacteria use binary fission to  grow, unlike eukaryote cells that have to … go through  meiosis/mitosis first.Bacteria do not have membrane bound  organelles, like mitochondria or Golgi apparatus, like eukaryotes  have. Many kinds of bacteria have motility thanks to their  flagellum.haracteristics of bacteria are prokaryotes, meaning they do not have membrane bound organelles, peptidoglycan cell wall, and asexual reproduction, meaning they only need themselves to multiply.

Animal and Plant Cells While a bacterial cell does have a cell wall and a cell membrane, it does not contain a nucleus. The bacterial cell's genetic material, which looks like a thick, tangled string, is found in the cytoplasm. Bacterial cells contain ribosomes, but none of the other organelles found in plant or animal cells.

A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host.

- A bacterial cell differs somewhat from the cell of a plant or animal. Bacterial cells have no nucleus and other organelles (sub-units within a cell with a specific function) bound by a membrane, except for ribosomes. Bacteria have pili, flagella, and a cell capsule (most of them), unlike animal or plant cells.An organism without a nucleus is called a prokaryote. A bacterial cell includes: 1  Basal body-this anchors the base of the flagellum, allowing it to rotate. 2  Capsule-a layer on the outside of the cell wall.acteria have pili, flagella, and a cell capsule (most of them), unlike animal or plant cells.

Bacterial chromosomal DNA with plasmid DNA. Bacteria contains a chromosomal DNA as well as a plasmid DNA, independent from the chromosomal DNA and is capable of replicating itself without chromosomal DNA. Plasmids are also found in some eukaryotes.

What is the difference between bacteria and viruses? Bacteria are cellular. They are prokaryotes, which means they don't have a nucleus, and the genetic material, which for all bacteria is DNA, is not separate from the rest of the contents of the cell by a membrane, as it is the case for eukaryotic cells, such as yeast, fungi, Protozoa, plants and animals.
