Question

Write a paragraph that describes where DNA is found inside cells and how it is packaged. Add a drawing to support your paragraph. Underline each of the following terms at least once as you use it: eukaryotic cells. and is for biomedical science

Answer 1

Answer:

This animation shows how DNA molecules are packed up into chromosomes.

DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.

Answer 2

To fit in the nucleus of every cell, DNA is densely packed. A DNA molecule wraps around histone proteins to form tight loops called nucleosomes, as illustrated in the animation. Chromatin is made up of nucleosomes that coil and stack together to create fibers. Chromatin, in turn, loops and folds to create chromosomes with the aid of other proteins. DNA tangles and damage during cell division are avoided by condensing DNA into chromosomes. DNA molecules are found inside  chromosomes.
