Chromosomes are made of a single strand of DNA.
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid, or DNA. Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique. The term chromosome comes from the Greek words for color (chroma) and body (soma).  DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide. Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. DNA. DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes 1 Your genome is made of a chemical called deoxyribonucleic acid, or DNA for short. 2  DNA contains four basic building blocks or ‘ bases ’: adenine (A), cytosine (C), guanine (G) and thymine (T). 3  The order, or sequence, of these bases form the instructions in the genome. 4  DNA is a two-stranded molecule. 1 DNA contains four basic building blocks or ‘ bases ’: adenine (A), cytosine (C), guanine (G) and thymine (T). 2  The order, or sequence, of these bases form the instructions in the genome. 3 DNA and histone proteins are packaged into structures called chromosomes. 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. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing Confidence votes 1.9K. Chromosomes are made of a single strand of DNA. There are also some proteins that are bound to this DNA in order to manage it and keep it coiled, these are also sometimes referred to as part of the chromosome. No. Chromosomes are made up of DNA and each chromosome contains thousands of genes. 1 person found this useful. Edit.

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.  Compaction of the duplicated chromosomes during cell division (mitosis or meiosis) results either in a four-arm structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends. Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome. A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism. Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome.
