What term describes condensed, coiled DNA during mitosis and meiosis?

• A. Chromatin
• B. Pedigree chart
• C. Chromosome
• D. Chromatids

Answer: (C)

Condensed, coiled DNA during mitosis and meiosis is called a chromosome. When a cell prepares to divide, the long DNA strands wrap tightly around proteins to form these compact structures so they can be accurately separated into daughter cells. After DNA is replicated, each chromosome consists of two identical sister chromatids held together at the centromere; even in this duplicated, condensed form, it’s still referred to as a chromosome until the chromatids split apart during division. Chromatin, by contrast, is the looser, unpacked form of DNA found during interphase. A pedigree chart is just a family-line diagram and isn’t related to the physical form of DNA. So the term describing the condensed, coiled DNA during cell division is chromosome.
