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.
â¢ Between promoter and first gene is a region called the operator, a sequence of DNA that can act in two different states. â The operator can bind a repressor (protein from the i gene; only role is to regulate transcription of another gene) and prevent DNA polymerase from binding the promoter.
