Question

write a paragraph that describes where DNA is found inside cells and how it is packaged. If desired, add a drawing to support your paragraph. Underline each of the following terms at least once as you use it: Eukaryotic Cells, Prokaryotic Cells, Organelles, Nucleus, Nucleotides, DNA, Histones, Chromosomes And he said use all of terms for the paragraph and this is for biomedical science pltw and use your own words too please

Answer 1

Explanation:

DNA (Deoxyribonucleic acid) is the repository of genetic information in living things. It is biological macromolecule made up of several units called nucleotides. In Eukaryotic cells (organisms with membrane-bound nucleus), the DNA is found in the nucleus. This is however different in prokaryotic cells, as the DNA is found in a nucleus-like body in the cytosol called the nucleoid. In Eukaryotes DNA is ordered and packed by structural proteins called histones. A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus, they wrap around complexes of histone proteins, giving the chromosome a more compact shape.

Answer 2

The DNA storages the genetic information. It is made of nucleotides that combine in different ways forming sequences that store specific information. In Prokaryotic cells, as there is not a nucleus, the DNA is on the cytosol in an area known as the nucleoid. On the other hand, in Eukaryotic cells, the DNA is separated from the rest of the organelles. It is in the nucleus surrounded by a membrane. For the DNA to fit in the nucleus, it has to be packed. Histones, which are proteins, wrap the DNA chains around them. As a result, they give support to a DNA molecule, also known as chromosomes.

The terms used in the paragraph refer to how DNA is in relation to other elements and according to the cell in which they are:

• Eukaryotic cells: They are cells that have organelles and different compartments.

• Procaryotic cells: they are cells that do not have different compartments. The DNA is in the cytosol. An example of these types of cells is bacteria.

• Organelles: the different elements that a Eukaryotic cell has. Each has a function.

• Nucleus: the place in the Eukarityc cell that contains the DNA.

• Nucleotides: it is one of the components of DNA.

• Histones: Proteins that compact the DNA in order for it to fit in the nucleus.

• DNA: desoxyribonucleic acid, a molecule that contains genetic information.

• Chromosome: a molecule of DNA.

All in all, after knowing what each concept means, we can relate them in a paragraph.
