Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP. Based on these observations, which of the following conclusions would the scientists most likely draw? A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
