As we learn more about genetics, this begins to look like an overly simplistic view of the concept of gene. The exact definition of the term gene is in debate at the moment, as is the use of the term at all in the future. The discovery of very short RNA's (miRNA, siRNA's) which influence gene expression (without translation into peptides) are part of this debate.
Definitions
A gene is a unit of heredity in a living organism. It is normally a stretch of DNA that codes
for a type of protein or for an RNA chain that has a function in the organism. All proteins and functional RNA chains are specified by genes. All living things depend on genes. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring. A gene is a unit of in a living organism.

Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring. A gene is a part of a DNA molecule that codes for a particular trait of an organism. It provides instructions on how to make a polypeptide. For example, one gene may code for the production of tyrosinase, which is an enzyme (protein) used in the synthesis of melanin (a pigment responsible for dark colors in skin and fur).
By the traditional definition, a gene is 'transcribed' into mRNA which is then 'translated' into a protein, which will produce the desired effect in an organism's cell. Some genes may contain instructions for the production of RNA that is not translated into a protein, such as tRNA, rRNA, miRNA and siRNA.
Conclusion
In essence, a gene is a section of a DNA molecule that has a unique and specific biological function.

How gene therapy is used to treat genetic disorders?
Gene therapy is a method that aims to cure inherited diseases by providing the patient with correct copy of the defective gene. There are four potential approaches to gene therapy:1)Addition of normal gene to replace the function of defective gene. This is gene replacement orgene augmentation therapy.2)Replacing the defective gene with the correct gene. This isCorrective gene therapy.3)Establishment of alternative pathways that bypass mutant genes function4)Change in regulation of normal or mutant genesThe first two are the basic approaches in gene therapy
Which of the following experimental techniques involves treating a genetic disorder by replacing a defective gene with a functional gene?
a new gene which codes for the protein that can repair defective genes is introduced.
Benefits of medical treatments that control gene expression?
I would guess that if a gene is not functioning normally then controlling the expression of that gene would be beneficial.
Alternate form of a gene?
Type your answer here... alleles
What is allele mining?
searching of gene..... or theallele of a gene which has some significant effect
A gene that can be masked by another gene is called?
A gene that can be masked by another gene is referred to as a recessive gene. This means that the trait associated with the recessive gene is expressed only when two copies of the gene are present.
