A gene is part of DNA. It is a sequence that specifically codes for a protein.
A gene is a section of DNA that codes for a functional product (i.e. a protein).
Genes control the functions of cells.
A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.
The non-coding sections of a gene are known as introns. The coding sections of a gene are known as exons.
I assume you mean the lac operon. The repressor binds upstream of the gene(s) in the regulatory gene region.
The process by which different cells express different genes depending on their needs is called differential gene expression
If you carry the sickle cell gene, it doesn't really mean much as far as your own personal health goes. Except that you are less likely to get malaria. However, if you decide to have kids, and whoever you mate with also carries the sickle cell gene (not the full blown disease/gene) , your child has a chance of having sickle cell disease (full blown).
How is a gene not expressed
Gene Okerlund goes by Mean Gene.
The cast of Mean Gene - 2017 includes: Gar Rogala as Gene Russet
Gene Snisky goes by Mean Gene, Gene Sinisky, Gene Snitsky, and The Foot Freak.
Mean Gene Kelton was born on April 10, 1953, in Mississippi, USA.
Transcription into RNA does not occur for that gene.
Do you mean allele? An allele is a different molecular form of the same gene.
Mean Gene Kelton died on December 28, 2010, in Houston, Texas, USA of road accident.
homozygous mutant means both alleles of a gene are mutated.
This means that the gene is physically located on that particular chromosome.
Gene Upshaw
A single abnormal gene produces HD. In 1993, scientists finally isolated the HD (Huntington's Chorea) gene on chromosome 4.
