PATHOLOGY

Detailed explanation-1: -Each chromosome consists of a single, enormously long linear DNA molecule associated with proteins that fold and pack the fine DNA thread into a more compact structure. The complex of DNA and protein is called chromatin (from the Greek chroma, “color, ‘’ because of its staining properties).

Detailed explanation-2: -Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.

Detailed explanation-3: -Structure of DNA. Most DNA is found inside the nucleus of a cell, where it forms the chromosomes. Chromosomes have proteins called histones that bind to DNA. DNA has two strands that twist into the shape of a spiral ladder called a helix.

Detailed explanation-4: -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-5: -Chromosomes are the structures found in the nucleus that carry the genetic code from one generation to the next. Chromosomes are made of two chemicals: DNA (this is where the genetic code is) and protein (helps to package DNA into nucleus).
