Detailed explanation-1: -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-2: -Chromosomes are found in the nucleus of every cell of our body and are made up of DNA, tightly coiled around proteins. We have 23 pairs of chromosomes altogether, and they can only be easily observed during cell division.
Detailed explanation-3: -Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the building block of the human body. Chromosomes also contain proteins that help DNA exist in the proper form.
Detailed explanation-4: -It is separate from the rest of the nucleus because of the specialized function. It does not contain chromosomes and is able to shuttle ribosomes and ribosomal RNAs out of the nucleus and into the cytoplasm where protein synthesis occurs.
Detailed explanation-5: -Chromosomes are present in the nucleus, not nucleolus. The nucleus is surrounded by nucleus membrane, s not cell membrane.
