Originally defined as the physical unit of heredity but the meaning has changed with increasing knowledge. It is probably best defined as the unit of inheritance that occupies a specific locus on a chromosome, the existence of which can be confirmed by the occurrence of different allelic forms. Given the occurrence of split genes, it might be re-defined as the set of DNA sequences (exons) that are required to produce a single polypeptide.
This is a part of a chromosome. Each gene is an instruction that affects - How we look e.g. hair colour, eye colour, skin colour, height, body shape etc. - How our body works e.g. how we metabolise foodstuffs, our intelligence potential, our personality traits, our blood group, our susceptibility to disease etc. - The vast majority of people have t â€¦
This is the part of the DNA molecule which carries the information defining the sequence of amino-acids in a specific polypeptide chain.
(Variation and inheritance) basic unit of genetic material that is inherited from our parents. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production
The unit of inheritance found in the chromosome. The linear units of heredity transmitted from generation to generation during sexual or asexual reproduction. Each gene is a segment of nucleic acid carried in the DNA encoded for a specific protein. More generally, the term 'gene' may be used in relation to the transmission and inheritance of particular identifiable traits. Minor gene: a gene that has small observable effects upon the phenotype Major gene: a gene that has large observable effects upon the phenotype....
For genetic engineering, the smallest portion of a chromosome that contains the hereditary information for the production of a protein.
Type: Term Pronunciation: jēn Definitions: 1.

This is a subsection of a chromosome. It contains just enough genetic material to manufacture a single molecule of protein (although it can do this many times).
