Gene expression

1) The process by which a gene's coded information is translated into the structures present and operating in the cell (either proteins or RNAs). 2) Gene expression is the ...

gene expression

Health care; Cancer treatment

The process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the ...

gene expression

Agriculture; Rice science

The process by which the polypeptide encoded by a gene is synthesized at the appropriate time, place, and rate. When a gene is "decoded" by the cell and a new protein is produced, ...

gene expression

Biology; Genetics

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding ...

acquired immunodeficiency syndrome (AIDS)

Biotechnology; Genetic engineering

The usually fatal human disease in which the immune system is destroyed by a retrovirus (Human Immunodeficiency Virus, HIV). The virus infects and destroys helper T-cells, which ...

polymerase chain reaction (PCR)

Biotechnology; Genetic engineering

A procedure that amplifies a particular DNA sequence. It involves multiple cycles of denaturation , annealing to oligonucleotide primers, and extension (polynucleotide ...

genotype

Biotechnology; Genetic engineering

1. The genetic constitution (gene makeup) of an organism. 2. The pair of alleles at a particular locus, e.g., Aa or aa . 3. The sum total of all pairs of alleles at all loci ...

collenchyma

Biotechnology; Genetic engineering

A tissue of living cells, the walls being unevenly thickened with cellulose and hemicellulose, but never lignified; it functions in mechanical support in young, short-lived or ...
