Concept 17 A gene is made of DNA. In the 1920s, experiments showed that a harmless strain of bacteria can become infectious when mixed with a virulent strain of bacteria that had been killed. The dead bacteria apparently provide some chemical that transforms the harmless bacteria to infectious ones.

DNA can be thought of as a code, containing all the instructions that tell a cell what to do. It is made up of genes. Humans have around 25,000 genes in total. You inherit half your DNA from your mother and half from your father, so you have two copies of every gene. Your genes carry all the information that makes you, you. They tell your body to have blonde hair, or brown skin, or green eyes for example.

This showed that the transforming principle is DNA — and, by extension, a gene is made of DNA. Still, many scientists were slow to accept this clear proof that DNA, not protein, is the genetic molecule.

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.

What chemical substances are genes made of? Genes are made up of a chemical called Deoxyribonucleic aci (DNA). DNA in turn, consists of two long polymers of simple units called nucleotides, with backbones made of sugars… and phosphate groups joined by ester bonds.

what are we made out of? Protein, Genetic code, DNA, Gene… A human being is made out of 100’000 billion cells… Each one has a nucleus, in which there are 23 pairs of chromosomes; one of the chromosomes comes from our mother, and the other from our father. A chromosome is made out of a long twisted thread of DNA (the double helix).

Each person has the same set of genes - about 20,000 in all. The differences between people come from slight variations in these genes. For example, a person with red hair doesn't have the red hair gene while a person with brown hair has the brown hair gene.. Instead, all people have genes for hair color, and different versions of these genes dictate whether someone will be a redhead or a brunette.

Genes are made of chromosomes, which are further made of DNA(deoxyribonucleic acid), while DNA is made of Guanine, Thymine, Adenine, and Cytosine.

Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell. This is called fertilisation. Gametes are produced by a type of cell division called meiosis.

A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes.
