Gene A gene is a locus (or region) of DNA that encodes a functional RNA or protein product, 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.egulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons.

Genes and Genetic Inheritance Definition: Genes are segments of DNA located on chromosomes. Genes exist in alternative forms called alleles. Alleles determine distinct traits that can be passed on from parents to offspring.The process by which genes are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel's law of segregation.enes exist in alternative forms called alleles.

Gene A gene is a segment of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes.

GENES GENES. A gene is a small piece of the genome. It's the genetic equivalent of the atom: As an atom is the fundamental unit of matter, a gene is the fundamental unit of heredity. Genes are found on chromosomes and are made of DNA. Different genes determine the different characteristics, or traits, of an organism.ll individuals in a species have the same set of genes: in peas there is a gene for pod color, a gene for plant height, a gene for pea shape, and so on. What makes individuals different is that a gene can have several different forms, or alleles.

Genetics Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar.

Genetics Genetics is the study of genes, heredity, and genetic variation in living organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems.rait inheritance and molecular inheritance mechanisms of genes are still a primary principle of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes.

- The modern working definition of a gene is a portion (or sequence) of DNA that codes for a known cellular function or process (e.g. the function make melanin molecules). A single 'gene' is most similar to a single 'word' in the English language. The nucleotides (molecules) that make up genes can be seen as 'letters' in the English language. Nucleotides are named according to which of the four nitrogenous bases they contain. The four bases are cytosine, guanine, adenine, and thymine.
