The Structure Of Eukaryotic Chromosomes

Eukaryotes include all living animal organisms other than the eubacteria and archaea. The eukaryote has a nucleus membrane that surrounds the nucleus in which the way they defined the

DNA is the genetic material that makes up the characteristics of all living organisms. While all human DNA is very similar in nature, there is just enough differences in

The DNA contains the information needed to make up our body and even our hands.

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

Our species all have the same DNA or same genetic code. DNA is kinda of a molecular blueprint for a living thing. Our DNA says that we are bacteria, we are unicellular, so we only have one cell in our body. Our DNA lives in the

DNA creates human beings. When we are created in the womb, we are just two strands of our parents DNA mixing together. DNA encodes the genetic information that is necessary for the growth, development, and reproduction of an organism.

One of the most significant accomplishments in forensic science is being able to use DNA, or deoxyribonucleic acid, to aid in criminal investigations. DNA is found in nearly all cells, both human and nonhuman. Most DNA is found in the nucleus, the center and most important part of any cell, where it is called nuclear DNA. Along with the nucleus, a small amount that can also be found in the mitochondria, called mtDNA. A single strand of DNA holds the hereditary information necessary for cell life to occur. DNA’s hereditary code is made up four bases: Adenine, Cytosine, Guanine, and Thymine. Humans have six billion bases and even so, 99.9% of all those bases are the same in everyone. With all of this, there is still room for variation in DNA

Every person has his or her own unique sets of DNA. DNA is a molecule that holds the genetic instructions used in the growth, development, functioning, and reproduction of organisms. The DNA coding is needed to produce proteins. These proteins are needed to catalyze reactions for cell replication. Furthermore, multiple cells create different body systems in order to maintain homeostasis.

Prokaryotes were the first organisms on earth. Millions of years later, eukaryotes would exist through evolution. Prokaryotic and eukaryotic cells are different in regards to structure and size. Prokaryotic cells are not as complex as eukaryotic cells.

Eukaryotic organisms have cells that contain a nucleus. Animals, plants, fungi, and protoctista all have eukaryotic cells. The eukaryotic cell has a plasma membrane as its external boundary like all other cells, but it also has a variety of membranes that divide the internal space into discrete compartments, which give them its unique feature, that enable the cell to carry out various chemical reactions or processes in separate parts of the cell, which all form part of the same system. The compartments in the cytoplasm are known as organelles.

Eukaryotic cells are unique because they have unique organelles. These organelles are membrane bound. These organelles have an additional transportation system. The membranous organelles are enclosed by the same type of material as the plasma. Therefore the can move through the cell easier. I thought this was really interesting because it like the organelles have like a car to use for transportation. The eukaryotic animal cells have many parts. As we go deeper will explain their importance.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

Eukaryotic cells - found in animals, plants and fungi. In eukaryotic cells, the DNA is sectioned off from the cytoplasm in its own membrane compartment called the nucleus.

Deoxyribonucleic (DNA) is the molecule that hold the genetic information of living things. In our body every cell contains about 2 meters of DNA. DNA is copied every time a cell divides. Deoxyribonucleic (DNA) is made up of two polynucleotide strands. Polynucleotide strands twist around each other, forming a shape that looks like a ladder called a double helix. The two polynucleotide strands run antiaparallel to each other with nitrogenous bases this means that the stands run in opposite directions, parallel to one another. The DNA molecule consists of two backbones chains of sugars and phosphate groups. The organic bases held together by hydrogen bonds. Although bases bonded together are termed paired

Due to the DNA’s specificity, samples can be utilised for identification. DNA is a nucleic acid composed of deoxyribose sugar bound to a phosphate group and one of four nitrogenous bases (adenine, guanine, cytosine and thymine). Each section of these three components are referred to as nucleotides, which are joined to the phosphate or sugar of another nucleotide by strong covalent bonds to form a backbone. The nitrogenous bases are joined to complimentary bases of another nucleotide (adenine with thymine, guanine with cytosine) to create a double stranded molecule (Figure 2). To complete the double helical structure, the molecule coils to compact it’s contents. DNA molecules can contain up to two million base pairs, with a human genome containing approximately 3 million base pairs. The random assortment of nitrogenous bases as well as the numerous mutations within certain DNA sequences, results in genetically diverese DNA molecules and genomes between individials.
