Q: What determines the length and thickness of dna chromosomes? Read this paragraph and choose the correct option from the provided answers: The degree of DNA coiling determines whether the chromosome strands are short and thick or long and thin. Between cell divisions, the DNA in chromosomes is more loosely coiled and forms long thin strands called chromatin . DNA is in this uncoiled form during the majority of the cell cycle, making the DNA available to the proteins involved in DNA replication and transcription. Before the cell divides, the chromatin coils up more tightly and form chromosomes. Only chromosomes stain clearly enough to be seen under a microscope. The word chromosome comes from the Greek word chroma (color), and soma (body) due to its ability to be stained strongly by dyes. Choices: - degree of rna coiling - type of dna - number of chromosomes - degree of dna coiling A:
**Answer**
degree of dna coiling

Q: What is the name of the disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall? Read this paragraph and choose the correct option from the provided answers: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. Choices: - arthritis - anemia - paralysis - atherosclerosis A:
**Answer**
atherosclerosis
