Binds to the DNA strand at a specific sequence of the gene called a promoter; Unwinds and unlinks the two strands of DNA; Uses one of the DNA strands as a guide or template; Matches new nucleotides with their complements on the DNA strand (G with C, A with U -- remember that RNA has uracil (U) instead of thymine (T))
Carbohydrates contain three major categories of molecules: monosaccharides (or simple sugars), disaccharides, and polysaccharides. 1. Monosaccharides: This group, also known as simple sugars, is the simplest carbohydrate form.
Glucose is the most common sugar type in nature. Cellulose (Î²-1,4- glucopyranose) and starch (Î±-1,4-glucopyranose) are the most common polysaccharides in nature. Glucose is also found in xanthan gum and konjac mannan.lucose is the most common sugar type in nature.
