If you unraveled a eukaryotic chromosome what would you observe as it became unraveled?

The chromosome would first unravel into supercoils, which would unravel into helical fibers. Then, the coils would unravel into clusters of histones and a single DNA molecule.

What organelle is similar to the Water Tower?
It is only similar to chloroplasts found in plants. It is thought that the mitochondria might have originated from early bacteria that became so symbiotic with their hosts, the eukaryotic cells, that they evolved and become indispensable energy-yielding structures within the eukaryotic cells (endosymbiotic theory).
What supports the idea that eukaryotic cells evolved after prokaryotic cells?
In a basic sense, eukaryotic cells are more complex than prokaryotic cells in their shape, function, differentiation and speciation. One theory that strongly supports eukaryotic evolution from prokaryotic cells is in the mitochondria. Mitochondria actually has its own DNA that is passed from generation to generation, The structure of the mitochondria is very similar to a basic prokaryotic cell, and some research has even indicated that the mito-DNA is actually similar to old bacterial DNA. This supports that perhaps at one point, a eukaryotic cell injested a bacterial cell, and instead of digesting it, the bacterium just stayed inside the euklaryotic cell and the two became one (this is a gross oversimplification, but the general idea remains the same).
What were the characteristic of mitocondria and chloroplast that caused scientists to hypothosize that they were originaly prokaryotic cells that were engulfed by early eukaryotic cells?
Following characteristics of mitochondria and chloroplast led Margulis (1983) and other scientists to hypothesized that mitochondria and chloroplast were Bacteria and Cyanobacteria that were engulfed by Amoeboid Eucaryotic cells and became symbiotic organelles. 1; Both mitochondria and chloroplast (M&C) are self replicating. 2; Both possess small circular DNA molecule similar to Plasmids. 3; Both possess an outer membrane similar to eukaryotic cell membrane. 4; Both possess an inner membrane simillar to prokaryotic cell membrane as it lacks sterols. 5; Both possess ribosome similar to prokaryotes and smaller than eukaryotic ribosomes. 6; Both produce their own m RNA and some proteins . 7; Both can produce their own ATP. 8; Both are semidependent on animal or plant cell. this hypothesis is called Endosymbiont hypothesis,
Is became a connective?
yes
During what era were the first one-celled organisms formed?
During the Archean Eon life started and was dominated by one-celled prokaryotic life forms. Eukaryotic one-celled organisms became dominant in the Proterozoic Eon. Multicellular organisms ruled the planet during the eon known as the Phanerozoic.
What is the answer to the Jumble puzzle on March 25 2012?
When junior got into the yarn, mom became… Answer: UNRAVELED, drama, elegy, vandal, trudge
What happened to the 24th chromosome pair present in other Primates when our ancestors became Human like as Humans have only 23 chromosome pairs?
Many scientists think the 24th chromosome fused together and that is why humans have 23.
In 1976 what did the US observe?
Our bicentennial, or 200 year anniversary (We officially became a country in 1776).
What did William III promise when he became king of England?
To observe people's rights and work with Parliament
After Pip's visit with Mr. Wemmick and as they were returning to Little Britain what did Pip observe about Mr. Wemmick?
The closer they got to the office, the more tight lipped he became.

Are bactirial cells larger than plant and animal cells?
No - quite the opposite. Eukaryotic cells (which include plant and animal cells) are vastly larger than prokaryotic cells (i.e. bacteria) - several orders of magnitude larger. The precise relation in size varies, but to give you a sense of the relative scales it is thought that some Eukaryotic cell organelles (mitochondria and chloroplasts) are actually derived from ancient prokaryotes who developed such a close symbiotic relationship with ancient eukaryotic cells that they became assimilated as a component. So, when you see a picture of an animal or plant cell where mitochondria and choloroplasts are shown, that's roughly the size of a prokaryotic cell relative to a eukaryotic cell.
Who first identified Saturn's rings?
Galileo Galilei was the first to observe Saturn's rings in 1610, but was unable to identify them as such.Christiaan Huygens became the first person to suggest that Saturn was surrounded by a ring in 1655.

Was daylight saving in use in Oklahoma in 1959?
No, northern Idaho (the part in the Pacific time zone) did not observe Daylight Saving Time between 1945 and 1948, and the southern part (in Mountain Time) did not observe Daylight Saving Time between 1945 and 1967.
Which planet was first seen by Galileo in 1610. He described it as the planet with ears?
Galileo described Saturn as having "ears" after he became the first person to observe it through a telescope. The existence of Saturn was known for thousands of years before Galileo.
