What is a gene? A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

- Definition of Gene Expression. A gene is a small piece of genetic material written in a code and called DNA. Each gene has within it a set of instructions for making molecules that organisms need to survive. Genes themselves cannot be used by an organism. gene is a small piece of genetic material written in a code and called DNA.

- A gene is a segment of nucleic acid that contains the information necessary to produce a functional product, usually a protein. Genes consist of a long strand of DNA (RNA in some viruses) that contains a promoter, which controls the activity of a gene, and a coding sequence, which determines what the gene produces.

- The process of gene expression is used by all known life-eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses-to generate the macromolecular machinery for life.n genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, i.e. observable trait. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.

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.he nucleotide sequence of a gene's DNA specifies the amino acid sequence of a protein through the genetic code. Sets of three nucleotides, known as codons, each correspond to a specific amino acid. Additionally, a  start codon , and three  stop codons  indicate the beginning and end of the protein coding region.

What is a 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.

Gene A gene is a locus (or region) of DNA which is made up of nucleotides 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. These genes make up different DNA sequences called genotypes.

- Best Answer: GENE A gene is part of a DNA molecule within the nucleus of all cells. Each gene codes for a particular protein.Thus a gene is a unit of the inheritable characteristics of the organism.Humans have tens of thousands of different genes; these determine the phenotype of the individual. ALLELE The sequence of nucleotides on a DNA molecule that constitutes the form of a gene at a specific spot or a chromosome.There can be several variations of this sequence, and each of these is called an allele.nswers. Best Answer: GENE A gene is part of a DNA molecule within the nucleus of all cells. Each gene codes for a particular protein. Thus a gene is a unit of the inheritable characteristics of the organism.

Where are the genes held in a cell? A gene is a segment of DNA that codes for a polypeptide or for a molecule of RNA, such as a transfer RNA (tRNA) or ribosomal RNA (rRNA). The genes in the nucleus are in chromosomes. A chromosome consists of a molecule of DNA (two after replication of the DNA) and associated proteins. Genes are segments of DNA molecules.

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. Most biological traits are under the influence of polygenes (many different genes) as well as the gene–environment interactions.

Genetics Trait 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.he 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.

What is a gene, post-ENCODE? History and updated definition Regulation is integral to many current definitions of the gene. In particular, one current textbook definition of a gene in molecular terms is the entire nucleic acid sequence that is necessary for the synthesis of a functional polypeptide (or RNA) (Lodish et al. 2000).

Gene Each gene occupies a certain location on a chromosome. Genes are self-replicating sequences of DNA nucleotides, subject to random structural changes (mutations). Hereditary traits are controlled by pairs of genes in the same position on a pair of chromosomes. These alleles may be either dominant or recessive.

The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.nce protein synthesis is complete the level of expression of that protein can be reduced by protein degradation. There are major protein degradation pathways in all prokaryotes and eukaryotes, of which the proteasome is a common component.
