What are Genes? A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes is the line of nucleotides on DNA and is used for the code for protein . Describe the relationship between the terms DNA, gene, chromosome, allele. Each gene tells the cell how to put together the building blocks for one specific protein. However, the gene (DNA) sits inside a different compartment of the cell.

These bases link in a very specific way: A always pairs with T, and C always pairs with G. The DNA molecule has two important properties.

It can make copies of itself.

If you pull the two strands apart, each can be used to make the other one and a new DNA molecule. It can carry information. The order of the bases along a strand is a code - a code for making proteins. Genes 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, to 25, genes.

These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.

Chromosomes If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand million miles long but very, very thin! To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes.

The packaging of DNA into chromosomes Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.

The sex chromosomes determine whether you are a boy XY or a girl XX. Inhe published his observations regarding patients whose urine turned black.

This condition known as alkaptonuria happens when there is a buildup of the chemical homogentisate, which causes the darkening of urine.

In most situations, excess amounts of amino acid phenylalanine are metabolised by the body. This led Garrod to surmise that the enzyme responsible for its breakdown must be defective in these patients. In addition, since the black urine phenotype was passed from generation to generation in a regular pattern, Garrod reasoned that a gene had to be responsible for the production of the defective enzyme.

He attributed a defective enzyme to a defective gene, suggesting a direct link between genes and proteins.

The Relationship Between Genes and Proteins Most genes contain the information require to make proteins. The journey from gene to protein is one that is complex and controlled within each cell and it consists of two major steps — transcription and translation.

Together, these two steps are known as gene expression. Although both DNA and RNA are made up of a chain of nucleotide bases, they have slightly different chemical properties. This is the second step in the production of proteins and it takes place in the cytoplasm.

Each sequence has three bases called a codon, which codes for one particular amino acid.
