Concept 17 A gene is made of DNA. 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.

- Chromosomes come in matching sets of two (or pairs) and there are hundreds — sometimes thousands — of genes in just one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribonucleic (say: dee-ox-see-ri-bo-nyoo-CLAY-ik) acid. Most cells have one nucleus (say: NOO-clee-us).

An Introduction to Molecular Biology/DNA the unit of life Genes are made from a long molecule called DNA, which is copied and inherited across generations. DNA is made of simple units that line up in a particular order within this large molecule. The order of these units carries genetic information, similar to how the order of letters on a page carry information. The language used by DNA is called the genetic code, which lets organisms read the information in the genes.

- A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before.

- Each gene has a special job to do. The DNA in a gene spells out specific instructions—much like in a cookbook recipe — for making proteins (say: PRO-teens) in the cell. Proteins are the building blocks for everything in your body. Bones and teeth, hair and earlobes, muscles and blood, are all made up of proteins.

DNA and Genes DNA and Genes. Genes are the blueprints of life. Genes control everything from hair color to blood sugar by telling cells which proteins to make, how much, when, and where. Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene.

What is a gene? What is a gene? 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. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases.

- 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.

Gene A gene is a locus (or region) of DNA which is made up of nucleotides and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. Most biological traits are under the influence of polygenes (many different genes) as well as the gene–environment interactions.

What is the relationship between DNA, Genes, and Chromosomes? Chromosomes are molecules that consist of a very long strand of DNA coiled many times, and a few proteins called histones which hold the whole structure together. To put things very simply, chromosomes are made up of genes and genes are made of DNA. gene is a section of the DNA that codes for something, like hair color. DNA is a double helix of nucleic acids. DNA twists and folds to create a structure called a chromosome. Source(s): B.S. in Neurobiology.

The Human Genome Project Completion: Frequently Asked Questions DNA molecules are made of two twisting, paired strands. Each strand is made of four chemical units, called nucleotide bases. The bases are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases on opposite strands pair specifically; an A always pairs with a T, and a C always with a G. The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.

Genes, DNA and cancer 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.And they tell your cells what sort of cell to be, how to behave, when to grow and reproduce, and when to die. Some genes control how much each cell grows and divides.our 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.

The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.The DNA double helix showing base pairs. The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.enes. A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood. Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes.

What is a gene made of? Best Answer: E.nucleotides A gene is a segment of DNA that codes for the production of a functional polypeptide or RNA. DNA consists of many nucleotides linked together (by 3', 5' phosphodiester bonds). So a gene is made of nucleotides. C. chromosomes That's wrong. A gene is a small segment of a chromosome, so is not made of chromosomes. Consider that humans have about 21,000 genes, but only 23 chromosome pairs. Clearly, a chromosome can contain hundreds of genes.
