- Answer Wiki. Chemical analysis of isolated chromosomes shows that it consists primarily of DNA and proteins with lesser amounts of RNA.The proteins are of two major classes : 1.basic proteins(positively charged at neutral pH) called histones and 2.non-histone chromosomal proteins.

List Ways in which Prokaryotic and Eukaryotic DNA Differ Eukaryotic DNA is organized in genes that each code for a single protein, although in some cases multiple genes might be transcribed at the same time. About 5 percent of eukaryotic DNA codes for proteins or RNA, but much of the remaining DNA helps identify gene and control gene expression.

- Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast.In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.nlike nuclear DNA, which is inherited from both parents and in which genes are rearranged in the process of recombination, there is usually no change in mtDNA from parent to offspring. Although mtDNA also recombines, it does so with copies of itself within the same mitochondrion.

Why is dna so important? Genomic DNA is located in the cell nucleus of eukaryotes, as well as small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid.

Each human cell contains roughly two meters of DNA.ukaryotes usually have a single nucleus, but a few cell types have no nuclei, and a few others have many. Cell nuclei contain most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes.

- It is interesting to note that DNA can be also extracted from mummies and fossilized dinosaur bones. In this lab activity, you will isolate DNA from epithelial cells that line the inside of your cheek. To do this, you will rinse your mouth with asaline (salt) solution, and collect the cells using a centrifuge.

Cytosol In prokaryotes the cytosol contains the cell's genome, within a structure known as a nucleoid. This is an irregular mass of DNA and associated proteins that control the transcription and replication of the bacterial chromosome and plasmids.

- The initiation of DNA replication is mediated by DnaA, a protein that binds to a region of the origin known as the DnaA box. In E. coli, there are 4 DnaA boxes, each of which contains a highly conserved 9 bp consensus sequence 5' - TTATCCACA - 3'.

Cells Can Replicate Their DNA Precisely During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands.

- The only exception is identical twins, who share 100% of their DNA. Each human cell contains three billion DNA base pairs. Our unique DNA, 0.1% of 3 billion, amounts to 3 million base pairs. That's more than enough to provide a profile that accurately identifies a person. DNA is often left behind at a crime scene. It is present in all kinds of evidence, including blood, hair, skin, saliva, and semen. Scientists can analyze the DNA in evidence samples to see if it matches a suspect's DNA.

- The human genome, for example, contains about 6 × 109 base pairs (bp) in the 23 pairs of chromosomes. Cleavage of human DNA with restriction enzymes that produce about one cut for every 3000 base pairs yields some 2 million fragments, far too many to separate from each other directly.

DNA extraction DNA extraction. DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods. The first isolation of DNA was done in 1869 by Friedrich Miescher.[1] Currently it is a routine procedure in molecular biology or forensic analyses.

Shared Flashcard Set Most of the DNA in eukaryotes is found in the nucleus, while prokaryotes, lacking a nucleus, have their DNA loose in the cytoplasm. Explanation: In eukaryotes, the genomic DNA, which makes up most of the cells DNA, is contained in the nucleus. There is additional DNA in the cells mitochondria, and still more in the chloroplast if it is a plant cell, but it is a very small amount.
