Detailed explanation-1: -The thread-like structure located inside the nucleus of cells of plants and animals is called a chromosome. The term chromosome was first coined by German anatomist Henrich Wilhelm Waldeyer in 1888. Each chromosome is composed of DNA wrapped tightly by proteins called histones.

Detailed explanation-2: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-3: -The concept of a chromosome A chromosome is a thread-like object (scientists literally called them threads or loops when they were first discovered) made of a material called chromatin. Chromatin is made of DNA and special structural proteins called histones.

Detailed explanation-4: -Complete answer: A DNA molecule in the nucleus of each cell is packaged into thread-like structures called chromosomes. A chromosome is made up of DNA which is tightly coiled or wound around many times around proteins known as histones, which supports its structure.

Detailed explanation-5: -Chromosomes are compact thread-like bodies woven together. These are formed at the time of cell division from chromatin material. DNA is responsible for storing and transmitting the hereditary information from one generation to another. They are located inside the nucleus of animal and plant cells.
