Structure and functions of 3 types of carbohydrates
Carbohydrates are the most abundant type of biological molecules.
Monomers of carbohydrates, monosaccharides, are simple sugars, and their primary role is to provide energy. For example, the brain requires a constant supply of sugar to meet its energy needs.
Structural elements of the cell walls in plants and bacteria and cell to cell communications depend on complex carbohydrate polymers such as oligosaccharides and polysaccharides.
5 key PCR components and their functions
5 standard PCR components play crucial roles in DNA amplification.
The polymerase chain reaction requires a set of appropriate oligonucleotide primers, DNA template and polymerase, a buffer and deoxynucleotides (dNTPs).
