Therefore, a broad, modern working definition of a gene is any discrete locus of heritable, genomic sequence which affect an organism's traits by being expressed as a functional product or by regulation of gene expression. Genome sequencing genome sequencing is figuring out the order of dna nucleotides, or bases, in a genome—the order of as, cs, gs, and ts that make up an organism's dna the human genome is made up of over 3 billion of these genetic letters today, dna sequencing on a large. Gene expression is the process by which genetic instructions are used to synthesize gene products these products are usually proteins, which go on to perform essential functions as enzymes, hormones and receptors, for example genes that do not code for proteins such as ribosomal rna or transfer rna code for functional rna products. A recessive gene is a gene that can be masked by a dominant gene in order to have a trait that is expressed by a recessive gene, such as blue eyes, you must get the gene for blue eyes from both of your parents.

Gene therapy is an experimental technique that uses genes to treat or prevent disease in the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient's cells instead of using drugs or surgery researchers are testing several approaches to gene therapy. Gene expression is the process by which the heritable information in a gene, the sequence of dna base pairs, is made into a functional gene product, such as protein or rna the basic idea is that dna is transcribed into rna, which is then translated into proteins. A secondary school revision resource for ocr gcse science about understanding ourselves and gene control. For most genes, we inherit two working copies -- one from mom and one from dad but with imprinted genes, we inherit only one working copy depending on the gene, either the copy from mom or the copy from dad is epigenetically silenced silencing usually happens through the addition of methyl groups.
We need to include something that restricts the definition of gene to those entities that are biologically significant hence, a gene is a dna sequence that is transcribed to produce a functional product.
