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.

Answer:

D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.

Explanation:

Ankrd is a binding chromatin, there is recognition that mutation is deregulating the chromatins. The proteins remove acetyl groups and then the region for DNA transcript. The recruitment chromatin is associated with proteins are enzymes which are chemical moieties.

Answer:

Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription

During photosynthesis, plants transform the energy in sunlight into chemical
energy by converting molecules of carbon dioxide and water into sugar and
oxygen molecules. What are two reasons scientists might use a model to
represent what happens during photosynthesis?
A. The molecules involved in photosynthesis are too small to see
with an optical microscope.
B. It is too dangerous to study the plants in which photosynthesis
occurs.
I c. Photosynthesis is too complex to be able to use experiments to
learn how it works.
D. The steps of photosynthesis occur too quickly to show each one
as it happens.
