The
biochemical material, either
RNA or
protein, resulting from
expression of a
gene. The amount of
gene product is used to measure how active a
gene is; abnormal amounts can be correlated with disease-causing
alleles.

Locus: 11p15.5 - The HBB
gene is found in region 15.5 on the short (p) arm of
human chromosome 11.

gene products are used within the
mitochondrion, but the
mitochondrion also needs
proteins encoded by nuclear genes.
Full article >>>A
gene product (usually
protein) that positively regulates
transcription. Activators may either increase binding of
RNA polymerase to the
promoter (closed complex formation) or stimulate
RNA polymerase to begin
transcription (open complex formation).
Full article >>>The synthesis of
gene products is driven by
kinases which in turn activate
transcription factors that mediate
gene expression.

gene products or
transcription factors are involved in very early cellular
differentiation and development.

biochemical used to identify or isolate a
gene, a
gene product, or a

Full article >>>gene expression The production of a biologically active
gene product, either constitutive or regulated.
gene splicing The enzymatic attachment of one
exon to another.

humans, but a few
evolutionarily related
gene products still remain to be
characterized.
Full article >>>Two additional
classes of
segmentation genes are
expressed after the gap
gene products. The pair-rule genes are
expressed in striped patterns of seven bands perpendicular to the anterior-
posterior axis (see the example, even-skipped).
Full article >>>Now the term
allele is used for two or more alternative forms of a
gene resulting in different
gene products and thus different
phenotypes. In a
haploid set of
chromosomes there is only one
allele at its specific
locus.
Full article >>>FUSION PROTEIN - A product of
recombinant DNA in which the foreign
gene product is juxtaposed ("fused") to either the carboxyl-terminal or amino-terminal portion of a
polypeptide encoded by the
vector itself.

organisms have evolved mechanisms of
gene amplification to provide
gene products needed in large quantities. These mechanisms include:
Elaboration of small "extrachromosomal" units that replicate to high copy number (r
DNA); ...

DNA is information, and information typically has a beginning point, an
inversion would produce an inactive or altered
protein. Likewise
deletion or
