Answer to Problem 1MM

Correct answer: The thread-like structures made largely of DNA molecules are called chromosomes.

Explanation of Solution

DNA is found in the nucleus of a cell. It is packed into chromosomes, which are thread-like structures. Chromosomes are made up of DNA that is tightly coiled around histone proteins for structural support. The chromosome numbers vary according to species; in humans, each somatic cell consists of 46 chromosomes (23 pairs). These include 22 pairs of autosomes and a pair of sex chromosomes (X and Y).
