Monosaccharides / Polysaccharides
Answer:
Explanation:
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function.

Answer:
B) their promoters have different affinities for RNA polymerase holoenzyme.
Explanation:
The housekeeping genes are the one whose products are involved in the vital metabolic pathways. So, these genes are mostly expressed at a constant level in the cells. However, the protein products of housekeeping genes exhibit variations in their cellular concentration.
The variation in the expression of housekeeping genes is regulated by the interaction between RNA polymerase holoenzyme and promoter.
The variations in the promoter sequences of these genes regulate the rate of the initiation of transcription by affecting the interaction between RNA polymerase-promoters. Certain promoter sequences facilitate the binding of RNA polymerase more than the other ones. This differential interaction regulates the rate of transcription initiation and accounts for variable cellular concentration of products of housekeeping genes.
