Blacks "live within two concentric circles of segregation" means
mr_godi [17]
<span>King stated this, he believed that black people were located at the bottom of the economic ladder. Their two circles of segregation were one that kept them prisoner based on their skin color while the other held them prisoner in poverty and deprivation. The average black person struggles to escape his circumstances but is hindered by these factors. He receives no normal education and no normal social or economic opportunities. When he attempts to try to better himself, he is told to lift himself up on his own by bis bootstraps, advice that is senseless considering he is often barefoot.</span>

Division of Labor

All GAL structural genes have UAS elements in their enhancer regions.true
insens350 [35]

It is true that all GAL structural genes have UAS elements in their enhancer regions.

UAS elements can be found in the enhancer regions of every GAL structural gene. An enhancer is a short portion of DNA (50–1500 bp) that can be bound by proteins (activators) to increase the likelihood of a particular gene being transcribed.

The GAL4-UAS system is a biochemical technique used to investigate gene expression and function in fruit flies. Two parts make up the system: the Gal4 protein, which is an activator of transcription in yeast, and the UAS (Upstream Activation Sequence), which is an enhancer to which GAL4 binds specifically to initiate transcription.
