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 genes are relatively short lengths of a chromosome, which is a mixture of DNA and proteins. For the cell to express a particular gene into a particular protein, it must first attach an enzyme complex to an appropriate spot on one of the organismâs chromosomes. That spot is called the promoter region. nucleotide base -- a ringed molecule containing nitrogen -- hangs off each sugar group, and itâs the sequence of these bases that contains the genetic code for creating proteins. Only 2 percent of a personâs DNA codes for proteins.
