Filler in textured paint works like spackling compound to fill the cracks, and dark, flat paint absorbs light to help conceal remaining blemishes. Be aware that dark colors will make your ceiling appear lower, so consider using very dark colors only in normally proportioned or narrow rooms.
In genetics, a promoter is a region of DNA that initiates transcription of a particular gene.
The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5â²) of the gene at a specialized sequence called a promoter (Figure 2a).In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements.igure Detail.
