Sentence examples for marker gene garnet from inspiring English sources
Expression of the imprint marker gene garnet was quantified both visually and through the use a spectrophotometric assay of extracted eye pigments.
Maternal inheritance of the Dp(1 f LJ9 mini-X chromosomes (Dp(1 f LJ9MAT) generate full expression of the marker gene garnet, whereas paternal inheritance (Dp(1 f LJ9PAT) generates variegated garnet expression.
Our results show that a reduction in dCTCF levels disrupts the maternal imprint boundary on the Drosophila Dp(1 f LJ9 mini-X chromosome, and consequently the marker gene, garnet, is silenced.
These dCTCF insulator sites, located between the centric heterochromatic imprinting center and the imprint marker gene garnet, could account for the sensitivity of the maternal imprint to dCTCF expression.
To determine whether dCTCF is involved in imprinted regulation in Drosophila as it is in mammals, we generated a dCTCF mutant allele with severe reduction in dCTCF expression and tested its effects on the expression of the imprint marker gene, garnet, on the Dp(1 f LJ9 mini-X chromosome.
In contrast to the effects observed when the Dp(1 f LJ9 is maternally imprinted, dCTCF mutants had no effect on the paternal expression of the garnet imprint marker gene.
Transmission of the Dp(1 f LJ9 mini-X chromosome through the female results in y 1 z a g 53d / Dp(1 f LJ9; +/+ mini-X chromosome-bearing male progeny with essentially wild-type expression of the garnet imprint marker gene.
To assess the effect of dCTCF on Drosophila imprinting, we used a well-characterized imprinting assay system, the Dp(1 f LJ9 mini-X chromosome, in which a readily visible eye color gene, garnet (g), is juxtaposed to an imprint control region and so becomes a marker for imprinting [ 29].
In the current study, Dr. Schatten started with 224 monkey eggs, mixing them with a neutralized virus that carried the marker gene.
He and his team members inserted what is known as a marker gene; the resulting banana, when placed under ultraviolet light, glowed fluorescent green.
In conclusion this growth factor augmented the levels tenogenic marker genes and downregulated non-tenogenic marker gene expression.
