The antibiotic rifampin inhibits the bacterial rna polymerase, preventing it from binding to the promoter region. this inhibits
a. translation
b. transcription
c. transposition
d. transduction
e. transformation

b. transcription

Explanation:

Transcription is the process by RNA is synthesized from DNA. It is carried out by RNA Polymerase enzyme which uses DNA as template. It builds new RNA strand in 5' to 3' direction from the template strand. A gene to be transcribed has a promoter region in front of it. RNA Polymerase is required to bind to this region to begin transcription. Once it binds to this region, the two DNA strands separate locally starting the process of transcription.

Rifampin inhibits RNA transcription by inhibiting bacterial DNA dependent RNA Polymerase. It binds to the beta sub unit of RNA Polymerase which does not allow it to properly bind to the promoter region thus halting transcription process.

explanation:

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
